Who doesn't like a cute kitten? The idea of the platformer is good, even if it was a bit hard to play since the physics is not perfect in my opinion. The kitten seems to be floating because gravity is too weak. Also the friction is too weak and the small square is sliding too easily. This is probably easy to fix. The black and white graphics are fine but the contrasts could be higher. As already have been mentioned the paperclip level (3) is too hard. The best part was perhaps the sound and music. Overall, a good start!
