You have made a great leap forward, using interactive introducing in the begining, using medailon like in The H.O.L.S., nice timed effects etc. The puzzle is also very good chalenge just if it is logical. Still miss the logic of putting a pot of mushrooms to papers making fire. If you can describe me this process closely, maybe i change my opinion that this is a huge mistake in this nice adventure. I really thought that i need to put that pot somewhere where the lightning can reach it...
So, take in consideriation to the next version patch this: 1. at least give player a slow match or some true source of fire... 2. make a sound effect when the sealed door is magicaly unsealed (also it will be great to use a random pattern e.g. bricks, if mention this). Good wishes.
