Hello @aracana , thanks for your review!
The main reason why there isn't any UI interact prompt is because then player could figure the puzzle out simply by running around looking for items.
I know it seems hard (especially the "spirits delight" could cause problems to a non-native English speaker, it means alchocol beverage, also there is a separate book that shows what to do with items) but that's really what we've been aiming for since the game itself is short (only 2 puzzle levels). I agree that the book clues need rework / retexture, maybe even include the picture of the item in question.
Also second level is much harder to solve(took about 1 hour and a half to our 3 testers)
Were the puzzles easy to solve the game would last around 10 minutes, that's the reason for the difficulty.
