Level 15 isn't that hard, but it's still hard, you need to throw your axe into the strange orange wall and fall in the hole, while you are falling, the axe will come back to you, then you press SPACE and throw it in the creppy skull, then, you can end it.
At the first time, i was thinking the game would end when darkness eat all the map, then a realized that i have a magic village, then, a magic tower, and... the darkness eated all. But anyway, this game is amazing and awesome, i just think the grass could be a little darker in some place, or have biomes too. But, well, i think this is for another game.
