Okay, I had some unexpected fun with this one, so thank you!
Projectiles work perfectly, the art is on point, music fits, honestly I really can't say anything badly about this. It feels professionally made, like maybe some little arcade game you would find inside another bigger game. The only thing missing (or I don't see it) is the theme, but oh well, who am I to complain about that lol.
Really good job, keep making games mister cowboy!
