Had some good fun with that one! :) Love how later levels require you to get creative, experiment and demand a lot of skilled execution (like timing the double jump correctly). My only complaint would be, that it took me quite a few tries in level 2 until I realized that you have to jump over the arrow to move the platform. Initially thought it would be just a directional marking on the wall. On replaying the game I noticed the level description beforehand, that's probably supposed to make you curious about that. So in the end it might be just about me being too lazy to read, but still: move the arrow a little bit more to the right, so you can hardly miss it when you decide to go for the goal and everyone will be happy! :)
