Heya ralvinty,
I didn't encounter any mayor bugs or crashes. The zoom looked a bit wonky though, but that was probably the tiles fault ^^
Overall I enjoyed it. Awesome custom art with the character sprites and busts -more of that please. And dodging bullets is quite the feat not gonna lie.
Mapping could use a little more work. If you can do pixelart, parallax mapping should be easy 4 you. Maybe you wanna look into that.
Our games are actually kind of similar now that I think about it... You should defiantly check it out! I think my kind of combat would suit your game better -with all the cool gunslingers and stuff. Once you get hold of the machine gun in my game, you know whats up ^^
