Interesting game play, after I got used to the controls it was feeling pretty fun to swing around the levels. Well done!
What was wrong with the controls?
It works fine, it takes a little getting used to the grapple mechanics. Also I could grapple to a block and just move while connected in one direction with no gravity affecting me.
Oh yeah, I discovered this bug a couple of hours before release :D
Ill tre to fix this now
