I finished the game and started for the second time and i can't reach hugly to trade the gem with !!!!!

**UPDATE** PLAYS PERFECTLY!!!!! patch fix and win 32 bit was all it needed and plays perfect on all of my 3 PC's Thanks so much! Says: Failed to start game. "UNKNOWN ERROR" everytime I click to run it. Tried all fixes from steam also installed on 3 different PC's as well.. Same error. I WAN'T TO PLAY THIS!...

I know the game is fairly recent and the lack of guide can be a bit frightening, but the achievements stats are scary. Are they working fine ? I watched a few gameplay vids and the limited save system is a disappointment. I don't myself walk for hours and/or discover cool stuff, but loose my progress cause I have to shut the game down without being able to manually save :( Some feedback/experience on the game overall would be appreciated, the reviews are anything but useful as of today ...

I was playing for second time. I chose to trade ring. I didn't lit torches this time (is this just visual or mattering stuff). I found that "troll" which asks to find altar, which I did but without any interaction. Restarting save did not help. Did I miss anything or it's bug?...

Think that everything is a huge calculator, right panel has to match with the left panel, each color is a math symbol / number http://imgur.com/a/ZswIX
