Unfortunately my guy ran out of oxygen and didn't make his escape.
First of all, I really enjoy the look and feel of the game! The low poly models of the base and the character are excellent and the animations turned out great too. This makes running around and collecting parts fun, until the player can no longer find the correct ones, that's when the change universe mechanic comes into play.
I think you definitely could have done a better job explaining what it means to change universe and I'm still not fully sure I understand how to play this game efficiently, since it seems a bit luck based (randomly spawning parts on change universe). I had a particularly hard time getting the parts of the 2 combo list to spawn (I assume you need 4 flat pieces, I only saw 1 in my whole attempt). Maybe going easy on the player and adapting spawn chances to the player's needs would make the experience less frustrating. Also a checklist of which parts you have already made would have been nice, because I lost track of my progress on the 3 combo list. Finally, I think you could add a transition and change the colour/texture of the terrain to indicate the change universe. (I know this is all a lot to do in just a one month game jam and my suggestions don't imply that there is not a lot of good stuff in your game already!)
All in all I think you came up with a really nice concept with an implementation that is still just a tiny bit rough around the edges!
