This is the very first time on this jam that I am seeing an idea of travelling between dimensions so Theme 5/5. I really like this idea. Game overall is quite fun to play but movement sometimes feels choppy.
What I liked:
1) idea of those 3 dimensions is just perfect - I really like it
2) shooting and walking is quite satysfying to execute, but
3) hand-drawn vibe graphics
What I didn't like:
1) Player has some strange interactions with walls sometimes - he gets stuck on invisible corners. One way to fix it in Unity is to create a new Physics2D material and set its dynamic and static friction to 0 and then assign it to a player's box collider
2) At the beggining when there's a screen with some dialogue it doesn't cover up entire screen in height. It takes 100% width but only like 80% of height which isn't a big deal but would be nicer to cover up entire screen
