Nice test, but we suffered from some skill issue.

The blue goop jumping in the end was set up wrong. You can't get the goo onto the right surfaces to actually make the jumps, and the closest we got had a buggy thing where it acted like there was a ceiling in the way when there wasn't (you hit you head on invisible nothing and can't bounce high enough to get atop the platforms.)

Consider putting all your coop levels into a collection so we can play them all. It's a pain to subscribe one at a time.

Great map! Keep up the great work.

Great map, like old ones. :)
