I tried playing it on Linux but it didn't go so well. Proton 7 wouldn't run it at all and latest wine starting to lag like crazy after only a minute so I didn't play very long.
I like the art style and the anime girl but the two don't match very well, need to make one look like the other. Check out Shogo if you haven't yet.
The weapons really need some juicy projectiles, focus on the effects and even just these two guns will be a treat to play.
