The fun of it wears off pretty fast for me. I'm probably almost done with it. The controls are just so bad that it's not that fun for me. I get that they're supposed to be bad, but it's not really enjoyable physics for me, just cumbersom platforming with a blob that barely can move.
The worst game I played so far was the soccer game where you have to keep balls in your part of the colored court when the timer runs out. No matter what I did, I don't think I ever once managed to bounce a single ball anywhere I wanted. I tried jumping into them, diving into them, grabbing them, over and over. They just basically randomly bounce around and it barely seems to matter that I'm even there. Wasn't that fun.
The game where you run through the walls wasn't that fun for me, despite being based off the hilarious MXC. You basically just hang back 1 ft. and watch people go through in front of you and then you wind up ahead of them every time without ever having to even guess.
The OST is a total Splatoon ripoff too, which is a form of flattery I suppose. But they lose a point for unoriginality on that front.
