A very nice twist on many other games...
This was a very nice concept and clearly was a lot of fun to play, however, I did notice a few problems.
Sometimes the rope would glitch and catch on something that wasn't there.
It seemed like I didn't even need to swing back and forth. As long as I held the right arrow, I would keep going in that direction. Momentum is key to making a swinging game more challanging.
Also, the levels were pretty repetative, and I found myself thinking "didn't I just play this before?"
All those aside, the game was very fun to play, and your idea was very unique and fun. I'm probably being a little harsh, but I think that if these problems were gone, I would definitly give you the ten that this game deserves. I would love to see this game on frontpage someday.
