Haha when I first saw this thread, my mouse was over the l so it looked like new level: poo and I was like o...kay...
KK I will rate and review it. If it's as good as Gym, it will definitely get a nice rating.
Okay, I am going to be straight-forward with you.
If this level either gets a check or no check, this doesn't get a check. For one, there is way to many little unknown oob trigger's that aren't clearly marked at all except for a no shortcuts help trigger on one end of the pool. Get rid of the oob triggers except for the one right on the bottom of the pool. Those can stay, but the others ruin the level. If you have various little friction platforms spaced far enough apart so it is a bit challenging, you are good to go.
I also like the diving board idea.
I like the jacuzzi and pool idea, but what are the platforms in the pool supposed to represent?? I also like the teleport things.
Also, if you are going to keep the finish hidden away like that, at least do not have it open to the marble rolling right off the edge. I would put in walls and ceilings.
Once you fix all those things, upload a new copy and I will rate it and give it a real review.
