Grow gourds in a graveyard, carry them to the pit in the middle, and throw them in for coins before the day runs out. 

A first-person game about tending a graveyard with a hole in the middle that eats.

What you do. Plant beds. They grow gourds on their own and level up as they grow. Pick a gourd up, carry it to the pit in the middle of the yard, and throw it in. Every one pays coins, and a long throw pays a bonus.

What is pushing you. The day runs on a timer. When it ends, night falls and you sleep in the bed to bank your coins. Fall in the pit yourself and the day ends there. You keep half of what you were carrying.

What you spend it on. The shop opens at nightfall. Money buys more ground to plant on. Sigils buy the upgrade tree: a vacuum that pulls gourds to you, a broom that blasts loose the heavy props lying around the yard, which the pit eats too, and eventually the pit itself, which you can drive across the yard instead of carrying everything to it.

What you are working towards. Everything you feed it makes it bigger. At rank eight the pit is full, and you climb in yourself to end the run. Or restart before that and keep your companions and a permanent growing-speed bonus.
