I encountered a bug the first time playing the game - after getting off the bus, I tried to wander off the path several times, and always got a "I'd better stick to the path" message. Then I arrived at the station and got the cutscene of talking to the blobby eye. When I gained control of my character, I talked to the eye again and got the same conversation as in the cutscene. Then I talked again, and it told me to look around for souls. I exited the station and wandered around, but the game wouldn't let me stray off the path like before the cutscene. I refreshed my browser and restarted the game, the issue went away.
As for the game itself, it's a series of fun little fetch quests which make logical sense. Cute graphics, a good way to spend half an hour.
