Pros:

1. Cool graphics style - it is simple, but still with style.
2. A bunch of gameplay elements.
3. When moving up it looks like hamster farting.

Cons:

1.  Levels are complex from the start. Start with simplier levels, so you don't need to put the controls as overlay on the screen.
2. Little bug: I had a gap between a bottom line of the screen and the ground.
3. Need a undo button, for 2-3 steps. Moves are slow, so if you are make a stupid mistake at the middle of the level - you loosing too much time.
4. Controls are little bit chunky. Try to store inputs from player when hamster still in the movement/animation.
5. When you charging the movement - there is only power, but not the direction of the movement. Try to replace these green squares with an arrow what will show where you will be at next step. (also will be cool if you will show the upcoming landscape changes and enemy collisions)

Can't made it througn 4th level. Feeling myself stupid. (:
