A browser build of Little Fighter 2, with network play for up to four computers in one match.
Player 1 moves with w a s d, attacks with f, jumps with g and defends with h. Player 2 moves with the arrow keys, attacks with /, jumps with . and defends with ,. Both can be rebound in settings, along with the names players are known by.
Pick network game, open a room and read out the four character code. Up to four computers join, two fighters each. Joiners connect to the host and to nobody else, which keeps one player's bad connection from reaching the rest.
The simulations run in step and compare a digest of the match every frame, so a room that drifts stops rather than playing on from different states. Input delay follows the worst round trip in the room. A player who leaves has their fighters dropped on a frame the host names, and the match carries on.
