This game design document provides readers with a robust understanding of this game's direction. The game provides a unique take on the theme, and it tracks well with the game jam's motivations. The production plan is also clear, and outlines many of the items that this team needs to complete. Overall, this is a strong entry, and I'm excited to see where the game goes.
Two notes for this team. First, I don't believe the document references sound effects or music. This will be important to consider as you move forward, since sound can complement the gameplay. Second, the team should remain mindful of scope as they move forward. There are several mechanics listed on the production plan that, on reading the document, feel like they may be secondary. I would try to determine early on the order in which some mechanics may be cut in the event of a time crunch.
Wishing you the best as we move forward!
