An open-source rhythm dungeon crawler in 16 x 9 pixels
I just released my latest Godot project, a rhythm-based dungeon crawler a la Crypt of the Necrodancer. The entire game plays out in 16 x 9 pixels because of a dare from my game dev group. I've open-sourced (MIT) the code and project files. Of course, the music files I don't own aren't included in the Github project, but I'm releasing the game's hand-crafted pixel sprites under CC0. The Github page also talks about some of the tricks you need to make the rhythm part of the game play nice with the dungeon crawling part.
An open-source rhythm dungeon crawler in 16 x 9 pixels launched on June 6, 2025 with 55 votes, #532 of 7,999 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
This is an open-source rhythm dungeon crawler built in Godot that displays entirely at 16 x 9 pixel resolution as a creative challenge. Players navigate dungeons while timing actions to music, similar to Crypt of the Necrodancer. The full source code and project files are available under the MIT license, along with hand-crafted pixel sprites released under CC0. The GitHub repository includes documentation about integrating rhythm mechanics with dungeon crawling gameplay, making it useful for developers studying these design techniques.

A rhythm dungeon crawler in 16 x 9 pixels. Made in Godot. - jgalecki/qrawl-tiny-mass-disco
Hello! Welcome to QRawl: Tiny Mass Disco, a 16x9 rhythm dungeon crawler. This game was created as part of the the Tiny Mass Games project, a loose collective of game devs focused on creating polished short-form games in two-month dev cycles. This game came out of our tenth season, and I decided to open-source the code after completing it. The official web version of the game can be found at https://joshuagalecki.itch.io/qrawl-tiny-mass-disco . There are two important things to understand in terms of designing a rhythm dungeon crawler. The first is the rhythm part of it. For the basics of the Conductor class and creating a rhythm game, I'll refer you to fizzd's legendary tutorial on A Dance…from github.com

Mini Metroidvania in 13KB of JavaScript2022 · arineonshark.itch.io · ▲238As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://github.com/arikwex/infernal-sigil NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller (https://github.com/lifthrasiir/roadroller) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural…
I built an interactive plotter art exhibit for SIGGRAPH2024 · lostpixels.io · ▲167I'm enthralled with using pen plotters to make generative art. Last August at SIGGRAPH, I built an interactive experience for others to see how code can be used to make visual art. The linked blog post is my trials and tribulations of linking a MIDI controller to one of these algorithms and sending its output to a plotter, so that people may witness the end-to-end experience.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
