This is really cool and a lot more fleshed out than I originally thought! It's pretty wild you made three full maps and all those different enemies. I like the style of the game and the art, it all fits together nicely. I'm also making a 2d shooter game, although its more of a boss rush game. It's called Shmooblin Blaster, if you wanna check it out and leave me some feedback I'd appreciate it!
