Diabolical!
The concept is really good, and the controls are super responsive. I managed to see the GG at the end, but I just couldn't climb all the way up to it... pure skill issue on my part :(
If you're open to some feedback, I would love to hear some sound effects. It would also be cool to have some kind of progression, like unlocking new textures for your brick or something similar. A very simple tutorial would help too, even if it's just to say 'use A or D' (this could just be in your itch.io page description).
Anyway, congrats on the game, I had a blast playing it!
