The demo used to stop after 11 games. It now stops after 1111 — at roughly five minutes a match, that's over ninety hours. Call it unlimited.
If you already hit the old limit, this applies to you too. Update the demo and your games are back.
We're doing this ahead of Steam Next Fest (19-26 October) — we'd rather you played the game than counted your remaining matches.
One more thing. The full version has online multiplayer for 2-4 players, and I'm looking for a few people to help test it before launch. If you'd like to play a few rounds with me in late September, come say hi on Discord: https://discord.gg/eeZbAe2vad
And yes, 1111 was chosen for a reason. More on that soon.
