Really cool mechanic of letting the players move the different block themselves and showing the names of the ones who moved a block the latest. The pixel art and the music are cool and the different blocks properties were simple but clever.
The only little issue i have, same as some others i saw in the comment is that when you reach the top there is nothing after the animation of the player character disappearing, no winning screen, no fading to black, or sound to let the player know that it ended, even though it feels like it. I expected something to come or that i had to do something to get a proper end to it, as i reached the top i saw one of the pillar having a block on top of it, the one in the middle, at first i thought the climb would continue after jumping on top of it or that it would be the end of the screen and game after jumping through it. Maybe adding something like mentioned above? the last proposition may not follow the idea you had in mind with what the animation of our character disappearing might means though.
Really cool platformer game with a neat idea!
