The title screen was fairly clever, with pressing the button to then show the actual game. I think this would be a better game without the power aspect, and just focus on the puzzle of the platforms changing the extension length based on the order of activation. I don't think the power bar really added anything to the game.
Also some work on evening out the player characters jumping and positioning would help make more clear the effect of each move. Beyond that I'm sure I found some solutions that weren't intended, such as extending a platform through all the other platforms, bypassing everything. :P
The way the credits were handled was also quite clever, though the player character continues jumping (and will eventually die) after the screen fades to the "Thank you", on purpose? :P
