Thanks a lot for trying my game !
Yea I figured I needed more upgrades but I had issue with balancing since I had no playtesters :(. The other motivation to not add new upgrades is that it's mostly in end game, and I wanted to enforce the fact that you consume the universe, and have a bit of a retrospection and void effect.
Unfortunately I started developing pretty late in the weekend so I couldn't really play on the "different gameplay" side and I went to the "big numbers go brrr"
