Gem Enchanter's Room

Access
In order to access the Gem Enchanter's Room, you need at least 200,000 gems. Otherwise, the room will be blocked off by a wall with '200,000' and a gem symbol on it. (Add picture.)

It is possible to glitch into the Gem Enchanter's Room by shift-locking through a corner. (Needs verification.)

Gem Enchanter
Moving close to the Gem Enchanter allows a window to open up, prompting you the option to rebirth. Clicking on the '?' in the upper left corner will lead to an info box that tells the sacrifices of rebirthing and the benefits of rebirthing.

Insane Mode
The door to Insane Mode can be accessed through the Gem Enchanter's Room as long as you have a key. In order to open it, press 'E' on the keyboard.

The Two Chests
No, they don't open. I tried.
