Gameplay : 4/5 - Dynamic and nice to play. Very classic but with some good ideas. One level in particular was using the attraction / repulsion forces and I found it very clever. But after that, that was more like a simple avoid the spikes action game.
Visuals : 5/5 - Impressed by the visual effects and the style
Sounds : 5/5 - Nice music, good FX
Enjoy : 4/5 - I really apreciated the first levels, a bit less the next ones (I prefer puzzles than action - my taste)
Theme : 1/5 - Sorry I can't see the link with the theme. I read the "explanations" but... no ;)
