The problem is that board game would change texture during the evening and pieces would begin to fuse with your hand as you moved them around. The landscape on the board would seem to shift by the latter stages and by night's end wing itself out the window you opened in yourself all unknowing.

A combination of activities last night has left me thinking it would be really cool to make a board game based on @jeffvandermeer.bsky.social's Southern Reach books. A bit like Wingspan, but with sanity checks.
