  • Robongus

    A bite-size social-deduction party game — gather in a lobby by code, ready up, walk a little 2D map, finish tasks, and find the impostor before they pick everyone off. Realtime multiplayer over host.collab.

  • Edge Invaders

    A 4-player twist on invaders: the aliens drift as a blob in the CENTER and up to 4 players sit on the four EDGES, all firing inward. Race for the most kills, but watch out — a shot that crosses the arena costs the player on the far side a life. Open it, share a room code (New / J

  • Versus Blocks

    Head-to-head falling blocks: 2 to 4 players, each on their own well, all racing at once. Clear lines to fire garbage rows at your rivals and survive theirs — last stack standing wins. Every board is authoritative to its own player and streamed live, so it stays smooth even in a c

  • Tic-Tac-Toe

    Play Tic-Tac-Toe with a friend on a shared board: open it, share the link, and take turns live. X and O are assigned by join order over host.collab, and agents can drive it too (play / reset / state). Standalone-safe: with no one else around you play both sides.
