This is what i came up with when i played map. Sorry guys if this is all a repost of pictures. When i first played it was very impressed.
The door in the picture isn't player clipped so you can jump on top of it.
The spawn door gives a no entry hand inside and outside and you are unable to walk back into that spawn door.
Door opens at super speed
A little opinion is make it a little clipped in this gap because when you do jump in between it, it will start to glitch your screen a little bit.
I know this has been mention before but the only leaks i could find besides the water falling through the crack. Here are all the leaks i could find though.
The mop is in the ground and the bucket is half way in the wall.
You are able to jump on top of these vents above the last cap.
I don't know if you can see but at the bottom of this moss texture it looks like it is starting the moss texture again. Its just a little piece.

More pictures are soon to come when i play it a little more in depth. Also for the trees i don't know if you want people jumping on top of it. you may want to clip the whole tree or put a push effect when you land ontop of the tree so you can't stay on top.
