Very well done action game! Very fun!
The slow down ability feels so satisfying when used near a large number of enemies. You just go zap zap zap and boom they're down!
The chatting on the side is so cute. I think I missed some lines while I was focused in the fighting but it was a nice touch.
The game is also well polished! Very nice work!
I think the only addition I'd suggest is a small tutorial screen showing at the start the controls and the crystals you're supposed to break to open the way out.
Great game!
