I'm almost done with my dice-rolling perfume game! It features a local multiplayer mode (2 players) as well as a single player mode. It's about buying different scents (with your dice) so you can make perfumes. At the end of each round there's a random event that you can choose to do (which impacts gameplay for the next rounds).
This was made in pico 8, a great tool for game jams as it forces to keep your scope small and simple :)
