This is a pretty cool game! I do wish there was some indication of when you hit an enemy (like a sound effect or a change in color or smthing), since I didn't always know if my shot landed or not. I like the different weapons, thats a really nice idea! Overall it could do with some more features, but as you said its your first game (just like me lol) I think that's fine, this whole game-making stuff is hard xd. Also the art looks really good, really fits the whole vibe of the game!
