Nice Game. Overall I do enjoy the difficulty. Though, I did get stuck in the level with the floating “LOL”s since I couldn’t quite grasp the timing to pass them. I really liked the feel of the way character controls. The first two levels where also very nice.
Here is some criticism too: I would have preferred the layer switching to be on one button only, instead of the two. Even after some time I still got a bit confused to which button I should press to get to the other layer. Another thing is that the collision for the spikes seems to match the size of the graphics exactly, which is a tad bit to large imo.
