I wanted to remind (or maybe even enlighten some of) you that before #SuperMeatBoy, there was #Gish. A puzzle-platformer where your character is a blob of a non-newtonian liquid.
Steam version allegedly sucks, but there's a FOSS version out there: https://github.com/freegish/freegish
Funnily enough it has #nix expressions for it. :D
