This is a game with a lot of potential. I think that the mechanic is beyond cool, and the difficulty is.. well... difficult. However, sometimes shooting the rope doesn't work and that lead to half of my deaths. If you want to have a good rage game, I recommend Snoman's video about Super Meat Boy. If just the small bugs were fixed and a bit of polish would be added, maybe a nice title screen and more features, this could even be a full game.
