The atmosphere is really spooky and I really loved it. Overall the sounds are just great and would love to have access to that track itself :)
Overall nice take on the theme, sometimes I had this weird lag, that would freeze the scene and I had to wait few moments for an unfreeze. But it is possible that this is just an issue of the browser and fullscreen mode? Not sure, nothing serious though. Did not made it till the end yet, as it is quite challenging to get past the dungeon.
Really great job done! Enjoyed this one
