took me a bit to realize I could read the book for the recipe (duh!), but once I got it it was very fun to run around picking up items. I especially found it funny when grabbing the piano and suddenly moving painfully slow xD
I wonder if you could've made a bigger level that started opening doors as you progress, and then it starts rewarding you for really learning the layout as it grows. It would be very exciting to go "I remember seeing a bloodied knife somewhere around here" and looking around frantically when it was under your nose all the time
not much more to say! just a short, fun experience, congrats!
