Hi eromop, we have noticed a decent number of users getting confused with the items and we are really sorry that it was confusing to so many of you. To quote my previous reply "There are some instructions at the bottom of the itch page since we have noticed that people are getting lost on the controls. To use items(if they have a use), you open your inventory then drag the item to the bottom right where there is a box which says use. This is also how you refuel your torch(by burning wood/paper in the top right icon), as well as reading the journals or getting descriptions(top left inspect). Hopefully that helps!" The inspect action actually does tell you what to do with each item or at least gives you hints, but you are right that maybe it should have been more intuitive or easy to find. Anyways, hope you enjoyed.
