The game's difficulty seems to vary a great degree depending on where the crystal spawns, some levels I spend like 5-10 seconds on and others i run out of time looking for the crystal or die to mobs. I think having some kind of hint or waypoint on where the crystal spawned but having an incentive to go to other places on the map for those berries for example would be a good idea. On a related note, with the current range in difficulty I found it really hard to get lucky consistently enough to get 6 crystals.
I wish the music, while really nice, had been slightly longer as I really noticed it looping pretty quickly.
I really like your idea of random powers but I found it somewhat difficult to safely use them and I would have preferred if controlling the powers wasnt tied to your movement keys and rather your cursor, a lot of the time i ended up just running and ignoring the powers unless i got something like extra speed or teleport.
the presentation however was really great: the environments, the cute character art and the visuals of level generation all appealed to me!
