Among the random-generated regularly floors in the gates, there are others-

CHURCH
The most common, the church lets you heal your monsters completely and save your game.

SHOP
Another common room, there is a merchant here that will sell you items and buy your items for the regular price. You can also save your game here.

TREASURE ROOM
Six treasure chests are here just for the taking, and who can resist? You can save here. But make sure it's not a-

MIMIC ROOM
Looks exactly like the Treasure Room, except there's only one chest. The other five are- MIMICS! However, this area's great for leveling up.

LOST FOREST
Hmmm, what a puzzle. You can't save here, and when you go off screen, it takes you to a totally different place.. Here-
Go right, left, then north-west, and then go in the second one from the left to escape this maddening puzzle.

CONVEYOR BELT
Annoying. Simply annoying. You can't save, and when you step on a conveyor belt, it'll lead you where it wants to. All this time being attacked by monsters. Find the right belt, and you've got it.

LABYRINTH
More interesting. No map to use, and it's, well, a maze. Ya' can't save, and there's three variations. Try to memorize 'em best you can!

COLISEUM
I LOVE THIS ONE! You go through three random foreign trainer battles, gaining two items each time you beat one. Remember, you can catch the opponent's monsters.... Once your inventory is full you'll be transported to the next level.
