24 alternatives to I AI-coded a tower defense game and documented the whole process
I'm a software developer with 20+ years of experience but during this time I never programmed any games, but I really wanted to for the longest time. With the advent of AI coding agents I thought that this is the best time to try and so I've learned a bit of Phaser.js (a Javascript based game engine) and entered Beginner's Jam Summer 2025 - a game jam for beginners in the game dev industry that allows AI coding. After around 25-30 hours (working mainly after my full-time day job) I managed to submit the game I called "Tower of Time" (the theme of the jam was "Time Travel"). You can play it…
Tower of Time is a browser-based tower defense game created with AI coding assistance using Phaser.js. Developed by an experienced software engineer for Beginner's Jam Summer 2025, the game incorporates the… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…

Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later) Please access it with PC, it's an HTML5 game: https://bytelegend.com/ I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm…

I'm using AI (mostly Claude) to create/publish a new video game every day This is day 33, first stab at the tower defense genre. Most of the games (including this one) I build with a single prompt. Rarely, a couple extra prompts are needed for bug fixes or to tweak the physics/UI. Extremely rarely, the AI has difficulty making the game work right (usually drawing it) and it takes a dozen or more prompts -- but the majority of the time, it gets everything right and makes a fully playable game first try Happy to answer any questions, just a little hobby project of mine I'm having…

I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

I had a dream on Nov 21, 2019 of a game. I woke up at 4:00pm that day, started programming it then, and 7 and 1/2 hours later, it was done. It's about you and a pink square going exploring. - otdav33/spelunko

Bleenk▲41I kept running into the same issue whenever starting a new project: the setup phase consumed more time than the actual feature work. Preparing boilerplate, restructuring directories, performing refactors, resolving dependency conflicts, and wiring framework logic consistently took hours before I could write meaningful code. Even with modern tooling, the early-stage workload was nearly identical across projects. To remove that bottleneck, I built Bleenk, an AI coding agent that operates directly on real repositories. Instead of generating isolated snippets, it performs multi-step…

Hi HN! This is my first game — something I’ve always wanted to do. It’s a small browser game built with Phaser 3, React, and the phaser template (https://github.com/phaserjs/template-react-ts/). I made it in 2 days (like 8 hours in total real time) using gemini-cli. About 90% of the code was generated with AI, but I learned a lot by making fine tweaks. It only works on PC since it’s a typical WASD + R (reload) shooter. I’d love feedback on: - Gameplay (is it fun, too hard?) - Ideas for new features Thanks in advance! ps: I used cubes as a prototype, but now I kind of…

You speak to the Oracle of Aion, an ancient entity with the power to affect the dungeon. If your wish is worthy, he may grant it, and the dungeon remember your wish forevermore. The changes will be visible for all players, forever. Play now in the browser! Free and no registration. Disclaimers: I singlehandedly made this game, it is in a crude state, the oracle works 50% of the time. Also, since your wishes turn into code automatically via AI, and literally anyone can wish whatever he wants, dont expect a polished experience. However, nothing like it exists and its free, enjoy the chaos!…

I built 1e4.ai - a chess web app where you play against neural networks trained to mimic human Lichess players at specific Elo ranges. There's a separate model for each 100-point rating bucket from ~800 to 2200+, and the bots not only choose human-like moves but also burn clock time, play worse under time pressure, and blunder in human-like ways. Live demo: https://1e4.ai Code: https://github.com/thomasj02/1e4_ai A few things that might be interesting: - Trained on almost a full year of Lichess blitz games, around 1B total games - Architecture is an a small…

Hi HN, I'm one of the engine programmers at All Out Games (https://allout.game/), a multiplayer-first gaming UGC platform where creators can make and play games with their friends. For scripting we wanted our creators to be able to jump in and create game mechanics without having to think about networking. If a developer had to manually send packets to/from client/server to get things to happen then we have failed. It is particularly bad if you are using AI tools because they struggle to keep in mind what code is meant to run where (client, server, or both) and…

I made a strategy game where you play the US or China through the AI race, 2026 to 2030, sixteen quarterly turns in the browser. One run takes about half an hour. At the start, the game seals two dice you never get to see. Inside: how hard alignment really is, and how fast takeoff compounds. You get eval reports, but only as ranges, and they flatter you most exactly when your systems are least aligned. At the end you get a debrief which shows what your evals said each quarter and also what was actually true. I lost every run I played myself so far. Every number in the game is source-backed…

Hi HN, I'm Oliver. I've been in the software and cloud engineering industry for a long time (28 years), and this past year genuinely changed how I think about coding. The bottleneck isn’t syntax anymore. It’s clarity. I now spend more time describing what I want, testing results, and refining instructions than writing code line by line. The spark for this project came from a presentation I gave at my son’s school in December, 2025. I expected mild interest. Instead, kids were completely engaged — hands up, pitching game ideas, iterating in real time. That made me question something I’d…

I come from a machine learning background - PyTorch code, leaving a training job running overnight, and Jupyter Notebooks. I hadn't touched much frontend before diving deep into start-ups. It was similar for my co-founder Nick, who spent time working on semiconductors. I started building, and noticing patterns in AI outputs. Enough to be able to understand how a hook works, how to manage state and why Typescript is great. But whenever it came to optimising a piece of code, debugging state issues or designing a codebase from scratch, my mind went blank. I went to ChatGPT Study Mode to seek…

I am a 50-year-old who left a FAANG Engineering Manager job to build a sci-fi game. I just released Outsider, a sci-fi narrative game with multiple endings. If you want to support my work, the game is now 15% off (https://store.steampowered.com/app/3040110/). I've always wanted to create a game. I moved from Brazil to the US to work at Big Tech, but after a career of customer focus, mission alignment and 360-degree feedback, I wanted to experience solo game development. While FAANG can be soul-crushing at times, I had a great manager and an amazing team. The pay and…

Hi HN, I'm the creator of this project. For the past months, I've been working on building an AI agent that could move beyond simple generation and tackle inventive challenges autonomously. The core idea was to create a system with a "metacognitive loop"—the ability to recognize when it's stuck on a fundamental problem and then launch a sub-mission to solve that specific bottleneck before continuing. The linked article is a deeper introduction to the system's architecture and a snapshot from a recent run. I tried to design it to be evidence-grounded and self-critical to avoid the pitfalls of…

Hi HN! On Sunday I spent a couple of hours building a short 2d platformer ("Prince of Persia" style). What's interesting is how I built it. I went for a zero-code approach, and built the whole thing using OpenAI Codex CLI and agent skills (with the progressive disclosure paradigm). You can play the game here: https://acatovic.github.io/gothicvania-codex-demo/ You can see the full code, agent skills and a complete writeup here: https://github.com/acatovic/gothicvania-codex-demo Some takeaways: * This was one of the most enjoyable experiences ever! *…

I started off with a simple goal: port the game Soldat to Typescript. I ended up not only with the game, but with a full system to train AI bots to play my own game, building a neural net to train new bot AIs from tens of thousands of simulated matches with different strategies. It also runs live all the time on my website and has a news dashboard and you can replay any game exactly. It all was a very fun way to dig into Fable's capabilities. The bill if I had done this with API billing? Nearly $2000.
