This game was very fun to play, and very unique. It fits the concept well. It was more polished than I expected. I recommend updating the thumbnail and screenshots, I think the game is better than it sells itself to be.
It was challenging, but just the right amount; new concepts introduced the further you get, and even some trolls in the later levels. The art was good, the music fit the serious and focused nature of the game.
A very good game!
