I really like this idea. A game where swinging affects gravity and allows you to rotate the world is absolutely great.
However, I struggled quite a lot with this game and didn't get very far because I died a lot. My main problems were that I couldn't work out how to swing on the rope, and I struggled to understand how gravity got changed. I guess down became the angle of the rope with what you stick it to? I also managed to get stuck at the beginning by swinging back and rotating the level 90 degrees and falling to the left from the start position. I then couldn't go anywhere or rope anything.
Control gripes aside, I did enjoy what there was and would really like to play an updated version with tweaked controls to make it easier.
