I’m taking a stab at the final sequence of (9) worlds for this project, and how they tie together.

1. Hall of _________ (intro)
2. Go go go
3. Yes No
4. Shooting Gallery
5. Gravemarket (HUNGRY)
6. Eat everything
7. Pied Piper / Tower – Babel – Sacrifice
8. Mt. Elephant Mine
9. Dying in bed + Arcade (outro)

I tried different consumption methods, such as forcing the user to put an object on their head, attempting to locate where the edible object is in space, etc… but I think I’m going to go with this dead simple, kind of ridiculous solution:
The edible objects can be attached to the head (like a hat), and when that happens, I trigger the eating function. 
The only real downside I’ve found is that if Horizon is running slowly, the food sticks to the player’s head for a second before disappearing.
