It's a little long. Got me frustrated because I keep dying in the last room and then have to start over and do the whole thing. A number of the puzzle elements are skippable, though. For instance I never needed the first pedistal button or elevator or light bridge in the first room since I could portal to whever I needed to go.

Thanks for commenting. This was my first map, took my 4-5 hours to complete. I was afraid it would be too frustrating and messy.

Was a long chamber but not too frustrating. I loved it, good work!
