Omg tysm for the feedback! Im so happy the game is fun hahahaha. Luckily I can change invulnerability frames easily to be longer haha, won´t do that during the rating period but maybe I will continue working on the game when the jam ends! I just had so much fun making it, that maybe I will try to make a mobile version or something like that. I wanted to make more items, and make like "special" items that you could only pick up once that changed your bullets or gave you special powers or something, but I run out of time. Seeing that people like the game and that I love working on it so much I will probably do the mobile version, just the 64x64 game in the middle and some layout with buttons on the side, everything with nice looking low rez pixel art. I could even add more playable characters with unique habilites, progression etc.
