This is really fun, i enjoyed it a lot :3

Very nice artwork and music. I like the general idea. :)

I like the idea of scaling the size by combining tetris and size difference for the player. I could not really aim and rotate the blocks smoothly though but it's okay. Might be nice if we have more clear instructions to go through. Overall good job for the game! :)

Very good idea, the "tetris" part speed is really too much, cannot aim correctly. And it took me three run to understand that the objective is to climb with the secondary mode.
But it's small problems comparing to such good visuals and audio!
