Finally got around to playing this one. I was sooo lost in my first playthrough I just quit and uninstalled but I powered through it and did surprisingly most of it without walkthroughs (i only needed walkthroughs at Kaptar because I kept getting lost). Decent level design, brilliant puzzle design, great if you're a spatially oriented person like myself. Discovering the mysteries of Hunrath and the other worlds was also extremely charming, and the FMV was really funny.

Downside is there's just tooo much walking. Ugh. Trust me it gets annoying especially towards the end at the Guantlet (you'll know it when you see it)
