Very cool demo! The overall presentation and the menus were very impressive for a gamejam game. The story looks interesting and the bird as a recurring character is a neat idea. Loved the player sprite and the music, especially the transition at the end of the demo. The 3D backgrounds were nice too, although a little bit of light around the player in dark areas would have been nice.
It was a bit hard to figure out all the controls, especially for zero gravity (doubly so because there was no clear indication when the player was in "zero gravity" mode). Though I assume that's partly due to time constraints and giving the player all the abilities in rapid succession that would normally be spread throughout the game.
Sucking out energy from devices is a cool mechanic, though it didn't seem to come up again after the beginning and my energy seemed to regenerate on its own just fine. Also, I personally think LeftClick to aim and RightClick to shoot should be reversed by default, though that might be just me.
Either way, very impressive prototype with lots of potential for a full game!
