Hi devss, soo im having a lot of fun in the demo, and i found out this bugs, and I wanted to report then to you to help in the game development :)
In the castle , as you defeat the ciclop, if you turn back in the hallway with the rocks, and come back to the place that you fight the ciclope, the crystals will be turned down and the hallway will be free.
When you are in this room(http://prntscr.com/pd77l0), if you turn back, you are teleported to a forest(http://prntscr.com/pd786b).
On the final battle with Mariah if Gershom get's KO'ed by her, when he come back to the place that the fight will happen, the fight is skipped directly to the cutscene where Gershom wins the fight.
And the other one is on the secret passege that you find mariah notes. when you get out and go back to the main path, the crystals resets and now you are locked in that room.
EDIT: Later on, battling Mariah i got this error when i used a fagoit.(Edit 2: I noticed that in some fights, like the mariah one(not the final battle tho) MPs itens doesnt work at all, and sometimes, they got this same error.
