oh my god YOUR ART IS ADORABLE!!!!! I LOVE IT. and i love the multiple different styles on display. This game has a lot of character.
This game is pretty clearly unfinished though, sorry. My playthrough ended when i left the room with melle too quickly, which caused all room triggers to break? i think? i dont know LOL.
anyway uh yeah i dont really know what to say about this game LOL. For your sprites, you need to import them differently so that they stay pixelated. Reply here with what engine you used and i can tell you how (if you used unity or godot)
your battle system needed something extra with the shooting mechanic, maybe a cooldown or a "total shots on screen at once" limit. As-is, it encourages constantly mashing space.
your music is great. thats all. just great.
this game has a lot of soul, even if as-is it's buggy and lacking QoL (like moving diagonally). I want you to keep making games, i think with better technical knowledge and experience you'll make something really good
