That's unusual. What browser are you using?
Sorry, it was a problem on my end apparently, I played the game and its amazing! Reminds me of Lemmings in the old days. Very beatiful art and the music is perfect for it, sometimes they get stuck but overall the gameplay is outstanding, one of the best games Ive rated here. There is a bug on the first level, you have to place all the ropes for the level to finish, took me a while to find it lol
