That is quite (too) short... First, there's a howl and it kill me to touch this animal (why ?). I just go to the right and I win the game (that's it). The aesthetic of the game were... not... good... at all... The sprite were not fluid enough for a good visual experience, the blocks were... blocks an why do an howl kill an elephant already?
To finish this game, you just got to walk to the right... That's it...
Oh! I've almost forgot to say that... There's no actual riddle...
