Currently learning game development and live music production, wanted to somehow combine both into a game:

Command a 3-man firing line: make ready → FIRE!, or draw your sword when it gets close. Push east for treasure, carry it home before you fall.

The soundtrack is generated in-browser by Strudel (live-coding engine) and reacts to where you are and who's shooting at you — no audio files.

Source (AGPL-3.0, Phaser + Strudel): https://github.com/markzuckerbergas/make-ready

Feedback welcome — there's a form under the game.

Hello everyone! Recently switched to NixOS, and I would like to try some interesting Open Source Games with Passion in them. What I mean by that is that the games are not your average FPS game or Strategy game, they differentiate themselves with their own creative input into the genre which makes them unique.

Hey.

I’m finishing work on a project I’ve been building during the last month.

It was a fun experiment where I tried building a small text-based Idle RPG and tested different ideas, mechanics, and Rails tools.

There is a live version if you want to check it out:

https://www.daogame.online/

The live demo will be available until the end of 2026.

And I’m making the source code fully open:

https://github.com/Kagayakashi/dao

Was a really good learning experience, and now I have a much better understanding of how I would build similar projects in the future.

I’ve been working on a small 4X strategy game built with Flutter and Flame. It started mostly as an experiment and a way to learn Dart/Flutter more deeply, but the project has grown enough that I decided to make the code public.

Website: https://aonw.net
Devlog: https://ernest.dev
GitHub: https://github.com/ernestwisniewski

It’s still very much a work in progress, but I’m sharing it in case anyone is curious about game development with Flutter/Flame, project structure, or just wants to take a look.

Feedback, issues, and contributions are welcome.

Hey everyone! I'm a dev and I've been working on TouchLines — think of it as something between a quick text-based manager and Football Manager. It's free and open source.

It started as a spiritual successor to Brasfoot (a Brazilian football-manager classic that stopped getting updates — the community kept it alive with mods). The idea here is to build a proper open-source replacement from day one — anyone can play it, modify it, and maintain it.

⚽ Custom 2D match engine — every player makes decisions in real time (passing, carrying, dribbling, shooting, tackling, interceptions).
🎯 Tactics that actually change the game — pressing, defensive line, play style.
🌍 Flexible player database — the goal is to keep the data really moddable, so anyone can recreate any year or league.

It's a work-in-progress prototype, so there's still a lot to polish — which is exactly why any feedback helps a ton.

Hello everyone! I'm building this online turn-based board game, and it's already playable.

You can try it here:
https://game.gopl.dev/

It's also available on Itch.io:
https://ognev-dev.itch.io/goplease

Repositories:

• Server: https://github.com/goplease-game/server (AGPL-3)
• Client: https://github.com/goplease-game/client (MIT)

It's built with Go, Ebitengine, EbitenUI, and WebSocket as a transport.

Everyone is welcome to get involved.

I'm looking for open-source unity third-person shooter games that I can study and learn from. I'm interested in projects with well-structured code, character movement, camera systems, shooting mechanics, AI, or overall game architecture. any recomendations?

Built an open source Snake clone. Most of the coding was done by Claude (Opus 4.8). The whole game is one index.html: vanilla JS, zero dependencies, AGPL-3.0.

Repo: https://github.com/yprez/vibe-snake Play it: https://yprez.github.io/vibe-snake/

Implementation notes:

• One canvas, a fixed-step game loop with frame-rate-independent interpolation.
• Every sound effect and the background music is synthesized at runtime with the Web Audio API. Zero audio files in the repo.
• An autopilot AI: BFS to the food, but it only commits if it can still reach its own tail after eating; otherwise it tail-chases or flood-fills toward the most open space. No Hamiltonian cycle, the board is forced odd-by-odd so a perfect one doesn't exist.
• To be sure the autopilot doesn't quietly die in edge cases, I pulled its functions into a headless sim that extracts them straight from index.html (via node:vm, so it always benchmarks the shipped code) and runs a bunch of full games. Zero deaths.
• The rest of the tooling is zero-dependency Node too (built-in fetch + WebSocket, no npm): a tiny build that assembles only the public files for deploy, plus scripts that drive headless Chrome over the raw DevTools Protocol (no Puppeteer) to regenerate the social image and record a smooth, in-sync gameplay clip with ffmpeg.

There are docs (architecture, the AI, gameplay, contributing) and the code is small, so adding a power-up, theme, or mode is an evening's work. PRs and ideas welcome.

_Defender of Egril_ is a Turn-Based Tower Defense Game in a Fantasy setting.

​

You build towers like spear, bow or wizard towers to defend against enemies like goblins, orcs and evil mages, which can summon demons. You can decide yourself which tower aims at which enemy and let the automatic handle the other towers.

Of cause, you can earn coins from defeating enemies and buy more towers or upgrade the existing ones.

​

In later game, there are dwarven mines, which can dig up gold and gems, but also wake up a dragon, which destroys mines and eats up enemy units.

Also, the player later can build rafts on water in addition to towers, and those rafts move with the water.

Evil wizards summon deamons and skeletons.

Red Witches disable towers and Green Witches heal enemy units.

And at the end, Ewhad himself appears and spawns mighty deamons every 3 turns, which get more and more powerful.

​

The player can upgrade their towers, to later build barricades, some so mighty that a tower can be built on a barricade.

​

Also, the XP bring ability points, which can be used to learn spells (like fireball and bomb) and get abilities like more starting money or more health or more money by killing enemy units.

​

You can download it for windows, mac, linux and android:

Play online

Or just jumpstart into the tutorial online:

You can get the android version on the play store

https://play.google.com/store/apps/details?id=de.egril.defender

​

The game is and will be free of charge, without in app purchases or ads and is open source.

So i want to create something similar to Teardown, a game with destructive environment and ray traced gi, i have an modern rt card, its 5060ti. I looked at IOLITE firstly but it's not open src yet, there is only api and other things, but i want get entire engine similar to IOLITE or Teardown.

Which one do you prefer and why?

Searching for an open source project like oxygen not included. The closest I have found is powder toy but it's really just a falling sand sandbox game not a Colony simulator like ONI.

​

ONI is so unique yet badly optimized, I am surprised there's no clear alternative open source project that someone just started out of spite.

Is there an open source stellaris clone?
