SCRUB

You are SCRUB: A tiny robot built to scale enormous fish! (In more ways than one)

Objective:

Scrub off all the unwanted scales from each fish as you climb with your grappling hook and bubbly double-jump. You can stand on top of scales and jellyfish to catch your breath, but be careful, as you can't grapple onto the same thing twice! Reach the angler fish at the top and touch the bait ball to win. Can you collect all 16 scales?

Controls:

LMB or E to use Grapple - WASD to move - Spacebar to jump and double-jump

(There's a bug which causes LMB to fail sometimes, but the E key should still work)
