Nice concept! I liked how this game was both action-like and puzzle-like. It was slightly buggy (raycasts going through walls) but it was a satisfying game to play! I got stuck on the second room, though. Also, I understand how jams usually don’t have enough time to care about art but mixing resolutions in pixel art is a bad idea most of the time, so preparing two sprites of different sizes may have looked better.

I like the idea. It is the first game I have played in the jam that had shooting which made it feel unique. The game skips the menu screen when you first launch it meaning you dont see the tutorial until you finish the game. Also the game is short however this is fine due to the limited dev time. good game.

Hällochen,

The Shrink Mechanic is well executed and works fine. I would recommend havin the bullets disappear, once they exit the screen. You can easily shoot all enemies, while they are off screen, if you know where they are. Also, a tutorial of some sort would be nice. At least, a quick description of the controls on your itch.io page (You can still edit your it) 

Its really sad that the game isnt longer, because the mechanics you got down.
