All of the upgrades felt satisfying and noticeably better. Really fun!! Nice simple and clean aesthetics for perfect readability in a survival game. I got cooked by getting stuck between some enemies and they pancaked me so I couldn't escape, so a few moments of invulnerability/no collisions could have saved me there! But it was my fault to get stuck so it didn't feel totally unfair. The sounds were also really good. I had fun! :D
