You play against all players that are in the current
room, so there might have been someone in the
other corner of the level.
Also there was a bug in <2.1 which turned off
changing ganis when someone stands still for
5 seconds or so, so when someone stands still
for 5 seconds then uses the metris item then
you still see him just standing there
(if he stays there and you enter the level you see
it correclty but not when you are near to him
and watch him).

But this stuff about lag gave me an idea about
the bug with blocks shown after closing the
metris game: when someone sees you playing
metris and sends lines, then the blocks have
been displayed even if you have already
turned the metris game off (the blocks
have been displayed but in a weird way).
