I heard on Steam's discussion board from one of the devs that this game should be playable on the Steam Deck. There's one report on ProtonDB from a user who contacted the devs and they got it working with Proton.

If anyone else can verify, please do. Thanks. :)

I made the fixes, it should be running fine on steam deck and Linux now. If you have any trouble, please email us at hello@luminawesome.com and I'll work with you directly to fix it.

Thanks!
