Very interesting (combat) mechanic & cool minimalistic art style! I liked the particle effects, too. Subtle, but added much to the game. Once I've figured out that your telekinesis powers worked in an area (I could've known that earlier by looking at the circle - entirely my fault), I had a blast. It felt very satisfying to fight the enemies with your powers.
If the chests are supposed to hold loot (I did not find any, maybe in a future update), I would prefer to open them with a simple keystroke. But they were fun to use in fights, too. I liked your entry!
