The good:
Controls are fun if you figure them out and the visuals are pleasing. Also eating people with a cube and not slime. I think gelatine cubes are not getting enough attention compared to the slime.
The bad:
The game breaks if you exceed some ludicrious speed, speedrunning potential ruined :< but actually there are some problems with the collision when pulling yourself with the hook.
Other than that a very solid entry, though I'm very disappointed that you're not EATING the guy with the grappling hook but just pick it up.
