Interesting game! If you polished this one up for a full game it would be amazing

A  slight falling mechanic to the grapling hook would have been a welcome addition to the game. Nevertheless, I did manage to get occasionally respectacle speeds.

Very enjoyable concept, but plagued by a few technical problems -- the worst is the inconsistent pull on the grappling hook (sometimes I'll be holding the right mouse button for ages and nothing will happen and then I'll be whipped towards my target faster than I want). It happened enough that the game was pretty difficult to control and that really mitigated the fun concept of grappling around the city.
