Update 0.1.2

This is an exciting update for me because it almost entirely focuses on the upgrades and achievements. Instead of building the structure of the game I get to just make new content, and that is fun for me. I also love working on the structure though, so this update includes some important optimizations, and I try my hand at some shaders.

• New achievements
• New upgrades
• Better mucus drops

Still a lot of content that I want to add, plus some major balancing since I've never really played from the start or gotten much feedback on the progression. But I'm less embarrassed with the general state of the game. I'm extremely embarrassed with the idea behind the game.
