cool concept of a game, but it is too easy to cheat. example; to simply right click and then click the goal or click'n drag. both of these ways allows you to cheat very easily.
but when not cheating it is a pretty nice game, though it is too short so 4/5 stars
for those of you who find the last (level 20) level too hard..
you simply hold the up and the right button and keep spawning copy's that fall into the pit and eventually someone will get to the other side..
