I’m getting back to a project I started in 2024 but got to pause it (couldn’t find anyone to help me). It’s called SuperTux Smasher (formerly SuperTuxBattleMelee), a platform fighter featuring Tux and other mascots in the open source community
So far, we are three people working on it (the other two just joined very recently) and they even get to do a logo for the game. There’s also a sample design of the main screen, and we’re working on the menu and a stage
We’re also looking for other potential people interested. Just note that it’s likely going to be a pixel art game, so if you know how to use Aseprite or Libresprite, that would be awesome. Otherwise, you can go as composer or programmer. You’ll just need to know how to use C++ and Squirrel (it’s like Lua, but with a true object-oriented paradigm), the latter will be used for modding support
If you’re interested, the source code is here on Codeberg: https://codeberg.org/SuperTuxSmasher/sts-game


I can’t help but I really hope you will get a cool game !
I can only recommend to quickly have a working prototype with 4p and a single character.
As a reference, not an open source game, but a cool demake: https://www.supersmashland.com/ this low scope game help Dan to have a nice skeleton for its later game Rivals of aether.
