Hard, but not unnecessarily so
This game is so perfect in every aspect. It's creative, with both the gameplay and the digital-coins-as-platforms idea. For the first 13 or 14 levels, it was difficult, but not enough to frustrate me. I was getting ready to quit towards the end because it was just too hard, but then I checked my level and it turns out I had gotten all the way to 21! So I just HAD to go back and finish it. My only quip with this is that the least-animated thing in this game, besides plain blocks, was the character himself. The only thing that it does to move is widen a few pixels when it bounces off of a wall. You could have added a few frames of animation for the jump and fall, but decided not to. Overall, 5/5 and 10/10
