Liked the concept (racing against yourself) and the mechanics! (who doesn’t love a grappling hook?)
I would agree that the mechanics are a little finicky though, I made it as far as the level with the red floor where you have to grapple 3 times and I just couldn’t figure out a consistent way to do it :(
Also, I don’t know if it was intended, but if the level was hard I just waited to get the clock on the first run to give myself enough time on the second :P
Fun game!
