A very solid entry.
Gameplay:
A well made mechanics (I'm curious what was the third you were thinking about as there was one box locked). There is not much to critisize.
Graphics:
Simple graphics, but you made them really well looking with various particles and nice effects on leap jumps. Good job. You might thing of some glow, it would look really good as it takes place in space or something so stars would be a good inspiration.
Audio:
Music and it's transitions are really well made and I really enjoyed that. Sound effects are a bit too loud for that music (just my opinion), so maybe you could make some sliders to have influence on that.
Innovation:
Cool idea that can be well developed. Hope for more puzzle ideas and that third power :P
Theme:
Good approach to theme, tho more reference to bounds would be perfect.
Great game and hope you work on that :)
