Very cool, I got stuck on the chemistry mixing the anti- fire foam near the end. I am not sure why when I mixed the vinegar, soap and baking soda together it would just empty the glass. It might have something to due with different amounts of each item or perhaps I was just doing it wrong . I think I may have encountered a slight bug where when you start to play the harmonica if you click back to move around the room the music stops playing but after completing the puzzle is goes back to normal. The curser changes put me through a loop at the start as I was interpreting interactable objects as not interactable and vice versa. Graphics, cutscenes, puzzles are all very neat and I quite enjoyed the game. You could add a hint button that the player could use that would point them in the general direction but I don't think its overtly necessary. Fantastic work!
