Love Dogs, Love Metroid Vania, Love Games!
The Game Bugs out if you try to make it Fullscreen (Firefox) after that you can't use any Keys anymore, have to restart the Game and can only play in Browser Screen.
Cool Idea especial with the Stair walking PowerUp, since walking stairs is completely unnatural for a dog.
Great Job, would like to have it played a little longer but the game ended suddenly :(
