Theme: Shapes

Come up with a game that aesthetically, thematically or mechanically focuses on 2d or 3d shapes, their properties, interactions, arrangements, combinations, intersections, projections, associations, etc. The game does not have to be abstract or geometric, but it could be!
You have a whole week to come up with an idea and find the time to make it! The 3 hours is to sketch out whatever you come up with.

Make something fast and scope it down to the bare essentials. Share what you make however imperfect it is and have fun! Submissions that aren't games (zines, drawings, physical games, etc!) are very much welcome, submit anything you have and play what other have done!

You can take more than 3 hours.
You can submit late.
You don't have to be in paradise to partake
