Just saw this new indie dreamcast game project on Twitter, it’s a rogue like 3D dungeon crawler, the developer is Ross.codes and he said he’s gonna be doing a Kickstarter for the game in April 2023 I think. I jumped in the discord and downloaded the pre alpha demo and it was pretty fun for the little bit I played! You can find the link to his discord server on his Twitter if you want to download the demo and try it yourself!
