Our first Symposium of the decade will be on Baba Is You, hosted by Pat.  He says:

Baba is You is a puzzle game in which the player can directly alter the rules. At first, this simply means changing victory conditions to suit the player. As the game goes on, things get much more complicated. We will be playing the game with an eye to how the logic of the puzzles comes to reflect the logic of game development itself, especially code and overlapping rulesets.

Discussion starts at 8:30pm EST / 5:30pm PST, over Discord.
