Trailmarks – Huge, browser-based, Carmen Sandiego-style travel game

I'd love to have people test-play my Carmen Sandiego/Backpacker style travel game. It's a retro genre... but if you like geography and quizzes, you'll like this! It's a working alpha with most of the content I intend to add, but I need to have people give it a try now before I decide which directions to fully develop! I'm torn between putting effort into missions, more advanced in-game trading economy or creating more of a narrative. But I'm also curious if you get the navigation, if the core gameplay makes sense and if you want to continue playing, basically. Hope you find it worth…

In plain words

Trailmarks is a browser-based travel game inspired by Carmen Sandiego and backpacking adventures, combining geography and quiz gameplay in a retro style. Players navigate the world, completing missions and engaging with an in-game economy while testing their geographical knowledge. The game is currently in alpha and playable directly in a browser without login or payment, with the developer seeking player feedback to determine which features to prioritize: expanded missions, a more complex trading system, or deeper narrative elements.

    I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…

  • Automatically detect and patch walking-dead states in Sierra gamesAug 2026 · github.com · ▲161

    Hi HN, I've become lazier in my old age and struggle to replay my favorite Sierra games from the 80s and 90s because I keep getting into those situations where I need an item from 3 acts ago, I have no save game handy, and now I gotta make dinner. So I'm building the Lucasartsifier: a static analysis tool that decompiles Sierra resource files, automatically finds those states, automatically generates code to prevent the player from getting into those states, then emits loose patch files that can be placed alongside the original game resources. There's no game-specific code involved; all the…

    Hey HN, I’m the solo developer of Search to Play, a social bookmarking platform for gamers — kind of like Letterboxd or Goodreads, but for video games. You can log your games, track your backlog, write reviews, and follow others. I’m building this as an alternative to spreadsheet tracking or platform-locked tools (Steam, PSN, etc). Would love your feedback! Happy to answer any questions here.

    Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…

  • Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
