Works with wine version 8.19 staging for all the linux users. A native linux version would definitely be nice, but I wouldn't consider it critical to implement right now.
The menu select sound effect is pretty loud, and I think the textures could look a bit sharper, like what you could get from upscaling resolution in an emulator. Overall though, super promising and I'm glad someone is working on this!
update: no way, theres a linux version now! that is so very epic and cool
