Well,
I played this game 4 hours straight and finished it.
I tried to pass some levels 30-60 times. So sometimes its got frasturating but i managed to finished the game.
I totally recommend the game. I bought it with HumbleBundle.
Go buy it support the creator.

There is little to no story as far as i can tell.
Graphics are very good except when lava or some effect gets too close screen is starts to go haywire little bit after that.
Sound are very good and pumps you for the level.
I played and finished using only two abilities but i can clearly say for abilities there is a learning curve.
So get ready to rage little bit and master afterwards.
