What do you mean "More meaningful scary ambience"? It's PLENTY SCARY already.
The first game I played this jam that didn't explain what or how we got there, and its a plus point in this context. What are in the eggs? Who am I delivering to? I'm hooked to find out more!
I do hope you continue building on this. I think there's a lot of potential here for a experiential narrative game.
Edit: Also, personal thanks to fetse for catching a gamebreaking bug in my game before release. Appreciate it :D
