Wow, you did it? :D I was kinda worried that noone will even see the Underworld, because of how hard it is! I added the puzzle too late in the process and didn't have time to properly play around with the difficulty - it would probably be okay if the player was prepared for this by a few earlier, easier versions, though I'm not sure if I would be able to give the portal a proper meaning then. The second half was also kinda rushed, especially the ending cutscence, that I've done last night before the deadline, falling asleep on the keyboard :D
