Very nice game! I really liked the idea of playing with 0 gravity. The graphics and music are very calming. The controls are very hard to get used to, but it's ok for me. Maybe they should simplify it a bit - make the player move slightly in the direction of the mouse on a room. Also, I didn't understand what to do with the 2nd and 3D batteries :( You should make it more obvious where to put them, or add hints to prevent soflock. Anyway, I really liked the execution and the concept!
