I actually liked it. It had different elements and was interesting. I wasn't confused by the doors, but the first time the walk panel didn't popup, so I thought I had to do a diving jump for the companion cube and died :P .

On the other hand, well, it's been so long since I played so I don't remember what the evilmaster's specialty was. So I'll leave it at that :)

Err, well I got there but really it was just by aimlessly trying things until one of the doors turned out to be the exit. Different certainly, but confusing for me at least :)
