I like the game, especially with how the menu is structured.
I think you really needed to introduce the spikes more gradually. It took me a while to find out that they were actually hitting my rope, and even when I put that together, I still wasn't *entirely* sure that was the case. This is made even more problematic because the first level sets up the expectation that the rope is inconsequential. More visual/audio feedback would help in this department. Maybe something like the spikes cutting the rope? Pretty much anything to show that the rope is what's being affected.
