Some really cool ideas here, particularly love the knocking over platforms as bridges mechanic. I think the game looks good and performs well, control is generally strong as well.
Unless I was playing incorrectly, it seems a number of the later levels require the player to move backwards against the camera. I don't think this really works super well because as far as I can tell its basically impossible to navigate things "behind" the player. I think camera rotation or a redesign of these puzzles would be the best improvement for the game.
Overall, really enjoyed it! Keep up the great stuff
