Definitely still a work in progress.
You are a hoarder being delivered a constant stream of packages.
Arrow keys to move.
Pick up packages with 'z' and move them into your house and press 'z' to put them down
Each package is worth 100 points and you lose as many points as packages in a stack if it topples.
Stacks topple from the cat messing with them or you stacking more than 4 boxes in a square.
Topples also chain together if it falls on another stack.
Game ends when you are crushed by a package. (You can be crushed in the initial package landing zone sorry)
But you said it, it's still in progress, and i hope you keep on working on it since it's idea is fantastic!
Also, I love that its on pico-8. Great work!
