I like this type of look and vibe and the gameplay is very unique, I've never seen anything like it in fact, it gets a lot of practice to get movement right and I am not there yet but I'll keep trying.
My only problem was with the performance. My computer is not very fast but it usually handles 2d games with no issues. The literal mounds of bullet casings and the way this is handled seems to be what is causing this issue.
Overall, a very promising game!
