I'm glad if you liked the art and audio! Also that you found the Game Over screen cute. :D
I'm sorry for the massive FPS drops, those came from me not having time to actually playtest the game indeed, I didn't know quite that many bullets would end up on screen... It's nice that you viewed it as an extra challenge! I think double-dipping on the damage by shooting multiple targets is indeed the way to go, though I wonder if I should keep that or not when making a patch for the game. I guess it might be a fun thing to keep, being able to line up shots to hit multiple hurtboxes.
No worries on the cheese, there are unfortunately a bunch of "god spots" and stuff, too! I'm happy if you enjoyed the game.
