Some fun things I’ve made:
engine-game.com. Deckbuilding puzzle game with daily challenges.
Asymptotic analysis. A mystery-hunt style Dominion puzzle. [Collaboration with Vee Xing.]
reciprocity.io. Social network and matchmaking site with surprising uptake. [The original was a collaboration with Katja Grace and Stephanie Zolayvar but is now bitrotten from FB API updates. Buck Shlegeris remade it in 2021 and now maintains it.]
