Alakajam 2! The theme was "You can't see everything".
The second Alakajam!
I had this idea for a 2-player board game that should be easy enough to implement as an online game. However I ran out of energy and soon time as well. It was weird. I want to finish this so I can try it out vs other alakajammers, but my motivation has taken a hit. Will update this at some point, because I am curious if the gameplay is deep enough for the game to be still fun after a few games.
