This map needs some balancing and fixes.
There is really only one spot to successfully cade and it's the last room of the map where you can camp the big door.
I like it. I have liked the map so far, but everytime there are less than 10 players people will start ragequitting, because it's so hard.
So - I suggest you to move the slime room destinations back inside the secret. Floating mid-air is bad idea and it causes even more balance issues.
Remove those weapons inside the slime room secret. The map already has ammo for every weapon, which makes the map dozen times easier for humans. For me it's kinda overkill.
Add more reset time on the music button. I prefer not to listen to it at all. It's annoying when somebody is spamming it and I'll have to spam stopsounds.
The ending room has a wall you can see through.
