I really like this so far! Keep up the great work! Only issue is I got stuck early on. After following the sign down into the market area and starting the first level, I went north and the door closed behind me.
There were candles and colored pencils in the room. I killed all of the enemies but nothing happened. I saw another door north but it didn't open. I kept hearing what sounded like an enemy attack coming from the other side of it but not the enemy itself.
So I don't know if that was a bug and the doors were supposed to open or if there was something else I was supposed to do that I missed. Either way, cool game!
