It's a nice use of the theme and the control mechanic over the platform is kinda clever to. It took me couple tries to realize that the green arrow (in the second level) controls the platform and also the use of this control scheme makes me nearly to give up on the 5th level. The progression of the difficulty is pretty tight here ;D
Well, nevertheless i had fun.. except the 5 th level (maybe if you would use the idea later on, when the player has gained more skill, it would be "better)
Well done! :)
