The 2020 edition of the Creative Jam hosted by Poly Games and the NAD had "Strategy" as a theme. The team I was part of was mostly made of people who met on the site, it was composed of students.
 My team decided to create a game in which the player must cross a level by throwing lights to see and be able to move. The more lights are thrown, the slower the player can move.
The strategic aspect is the speed management and the fact that enemies can shut lights off. The player can only throw 3 lights at the same time.

 We wanted to create an experience based on lights and the management of resources. We also incorporated the following modifier "The more you use it, the less it is effective"
