Simple and fun, but sadly I've seen other similar games, I mean it's not bad that everyone get similar ideas but you know. In the other hand I quite enjoyed this, can't say this is too easy to play since on some levels I was like hmmm but got the hang of the game pretty quickly.
(also note one bug where you can push the groom with your rope when you don't even start the physics engine and the timer for him. You can just push him, if you would have found out about this bug you probably could have use it to your advantage to make it much different, using different tactics to levels and stuff and instead of the timer the rope could be not infinite, in other words, nice game!)
