I didn't even complete reading the game's name when I saw it was developed by LongAnimals. I instantly knew this game would be awesome. Half an hour in, I haven't found a reason not to be amazed :)
Actually, there is a way to beat the last level. You just run down the upper platform and perform a jump mid air. After you reach the snail thingy, you reach another level, "Mini Story" and it has music by ZeroPass, if that makes it more authentic for you! It really works. Try before voting this down :/
