Fun game! I think the entire vibe was pulled together by the artistic and audio choices that you made! Super cool, big fan!
Some pieces of feedback:
- Maybe you could make the sprites look more pixellated to bring the entire retro aesthetic to the next level
- Maybe you could incorporate different styles of the game..maybe different environments with sprites that act completely differently, or maybe a hard mode that makes sprites way harder than they are normally
- I was also wondering why I started at Stage 8 ? i think that's what it says when you first start the game
- Maybe adding like HP bars for the enemies or like at least some kind of animation that shows they're hit and not just absorbing the attacks could make it feel more polished.
I love the overall vibe and there's not much to say about bugs I've encountered or anything. Great game, all I want to see is more content (though there already is a lot). Keep it up!!!
