Cuby

Cuby is a rage game originally made in 2019 (This version is no longer obtainable). And, before you come at me, yes, it's technically c-uh-bi, but my logic says it's c-ue-bi. And, yes, it's technically a square, but squarey doesn't sound appetizing.

This game is meant to bring out the worse in someone's mind, being your generic platformer were you play as a cube named Cuby, trying to make it to the end of the harsh game the developers put it in.

(Also, game saves every 3 levels for added anger.)
