Congratulations! Im glad to hear there was no game breaking bug. I will get to the one in the labyrinth , though. To use the rotating pillar is not necessary to complete the game as you discovered, more like an easter egg, feature ;)
Glad to hear ;) I'll solve it and upload a new dist as soon as I can but may take a couple of days, have a lot at hand here - Iäll try to find some time during this upcoming week
