Reminds me of good ol' Micro Machines and has a similar charm to Nitrome games, well done! If you keep working on it I would love to see the grapple range extended a bit, currently if you're moving too fast it's difficult to latch onto anything, and if you're too close when you do get a grapple you'll spin so fast it's hard not to bump into the other swimmers when you release.
I'll catch you one day, Purple Frog Swimming Buoy Lemon Lemon Purple Frog!
