You already got past the golem area in that save. To proceed, you must go south from the golem, then east (if you want to, you can transform into a mouse to go through the bars, and get some info on what to do next before going east).
In the area where you use the short-range teleport, you must first enter the two room with the controls (north-east and north-west) to disable the mana cannons (the teleport anchor at the center doesn't become active until you have done that).
Anyway, if you don't want to mess with this, you can use this save instead (I played your save right to the point where you have to step inside the magic circle).
