Amazing game! Definitely one of my favorites so far! Art style is minimalist, but super cute and easy to parse. I especially like how the bullet slows down before impact. Would really benefit from some sound effects though. Unfortunately "Big Belly Eats" is bugged, but you can restart by pressing "R" - so no big deal. There is quite a bunch of new enemy types beyond that point: like gunners, guys with shields and hostages, that your are not allowed to shoot! Quite impressive for a 48h gamejam! Found my personal nemesis in the "Architecture" level however. Could not beat it and had to stop there. :(
