Bugs
Game screen should be 1280x720. Jump speed should be on a different layer.
Strengths
Platforms are well-drawn. Character has an idle animation. Small platforms are satisfying to land on.
Weaknesses
Without being able to see the jump speed it is hard to predict how high my next jump will be.
Changes or improvements
Could zoom out to see what is below me so that I can aim for a platform to land on. Could increase horizontal movement speed because it is hard to gain momentum on small platforms.
