The game ran smoothly and the physics for the hose were very easy to grasp. The online leaderboard was also a very nice addition. With some more gameplay and visuals this could be a very good game.
The grappling mechanic works much better than others I've seen although I wish there was an indicator when something was too far away. The rocket launcher doesn't seem to do much besides give you a boost, but maybe I just didn't experiment that much.
