Good game. Could definitely use some sounds. Is there supposed to be a win scene or anything upon reaching the top? I tried interacting with the thing on the right but nothing happens. I wound up just jumping off the sides of the tower.
Camera movement could use some tweaking. With the tiles and background it can cause a slightly nauseating effect when jumping or falling a long distance.
The choice to not have the player move with the left/right platform was a bit of a shock.
Overall very good game.
