Haha, when I make semi-public tests of the map, the n°1 way to make everybody rage on the server is to remember them that I was able to make it as Heavy.
So yeah don't worry, both the Forest and the Hospital are made so that any class can do it. It requires some thinking sometimes though.
Well, so here is the basic idea of how the map works: Akin to the late cp_bestinclass_v2, both teams spawn in a room, separated by a glass window, and each of those rooms has 5 teleporters and 1 gate.
At the beginning, the only available teleporter is The Forest. When the player enter it, he access the first room of the Forest parcour. Note that he can go back from this room to the spawn. To access the Forest's control point, the players must go through 4 "rooms" full of saw blades and such. The sawblades behave like those in koth_sawmill (noise, blood particles) but they don't kill the player. Instead, the player gets teleported to the entrance of the room and can directly try again.
The only way a player can die is in the Control Point room where the traps (and the Boss, Lil Slugger) or the other team's players who reached the room too can kill him.
When a team captures the CP, its players can directly access The Hospital, while the other must wait 45 seconds, unless they manage to re-cap the point, in which case they can go directly.
Each world has its own kind of traps (from saw blades to syringes, from mobs to ventilators), its own soundscape (the huge file size is half because of the music), then, when the End's gate is unlocked in the spawn room, the game becomes a CTF where the only team who can captures the Intelligence (self-made Bandage Girl model) is the one who owns the most control points. That's why the previous worlds stay always unlocked, so players can team to go and reclaim some of their CPs.
The game ends when one team has captured bandage girl 10 times (might change).
Oh and also, when a world unlocks, Its CP stays locked for some minutes to avoid giving sticky jumping demomen and soldiers and overwhelming advantage on Heavies and other class.
note: engineers won't be able to build in the 5 first worlds. For obvious reasons. Unless the map becomes a mod and I can control what kind of buildings they can make.
In short it is more of a party-game like map which gets funnier the most players there is. I hope I can show it to Team Meat once it's all over.
I'll wait a little before talking about the map on Facepunch. I want at least the first 3 worlds finished. Also, the feedback I want from TF2 players, I have it every days on the daily tests.
This allows me to equilibrate the map at each version.
Here I want feedback from "fans and players" of super meat boy :)
EDIT I JUST REALIZED YOU ARE THE CREATOR OF THAT HAKUREI SHRINE MAP, PLEASE LET ME WASH YOUR SHOOES.
Wait what? *checks TF2stats* WUT The map actually became popular!? I'M SO HAPPY

As a side question, did you find how to trigger the secret music?
