Found it!!!!!

Been trying to find this key for a while now. Pressing all the buttons at random in the one big and two little rooms. Can't find a second key or open any more small rooms. Totally stuck.

Anyone?

How many small rooms should there be? I've opened 2 and neither contain a key.

Hi all. I'm in the room with the floating blue crystal. There's a teleport puzzle to the right where you need to press a cracked stone to get through it and to the left I've got three rooms with buttons in them. The buttons open each others doors. The gate I'm trying to get through has a lock either...
