Solo dev here. Schmess is chess with the turn structure removed. Both players move whenever they have a free slot, and every piece freezes on a cooldown after it moves. It s on a half board, with 100+ puzzle stages. If two people played this over a physical board they d scrape each other s fingers raw - that s roughly the tempo.Plays in the browser, no signup. 29 stages free, one-time unlock for the rest ($3.99 / Rs 149). No subscription, no ads.It s the second of a few small-board variants I m building (halfchess was the first, more coming). Building a chess engine for a game with no turns turned out to be the hard part - I ve put the war stories in a comment below.
