I totally forgot to upload a linux or web build of my game *facepalm* but as a fellow linux-only user, I want to point out that you can use Lutris to play windows games. It takes care of handling the wine and proton compatibility layers for you, and it's what I've been using to play all these windows games without issue so far!
Edit: it's all free and open source
(I know you can't play my game, but if you ever try lutris or wine, you can check it out. I'll add a web version post jam: https://itch.io/jam/boss-rush-jam-2025/rate/3292792)
