I'm not that good at parkour and i didn't found this game to be hard, only the last levels were more difficult (i didn't tried the hard mode yet, but that is an optional mode). I liked the minimalistic textures and the gameplay was fun, and that's what matters. My only sugestion is that you add a game command that resets the current level, since you need to know which level you are to reset it through the change_level command and there are some possible softlocks, like the breakable blocks disappearing if you place them on a place where a wall appears if you interact with a button.
