Nice job. I think the puzzle/level design really makes your controls scheme scheme shine. The game overall is fun to play.
Also the cover art is really eye catching tho it doesn't really have much to do with how the rest of the game looks. That said I'm really impressed how appealing you managed to make those simple geometric models look through the use of lighting and colors. Oh and those electricity arcs are great looking.
There's only one minor thing I'd criticize.
The level that introduces the "grab" mechanic doesn't in any way require the use of it to be solved (also it's more of an "attract" than grab in a way that it functions).
