----------------- Left to do: -------------------
|
||||
Come up with a better scheme for internet play, as it is any latency will
|
||||
kill the game playability. Works fine on LAN though.
|
||||
|
||||
Figure out why matching doesn't work through a firewall...
|
||||
[Specific case is 2 machines on my LAN cannot be matched by a machine that
|
||||
is outside the firewall, and the firewall machine is doing IP masquerading.
|
||||
Net result is matcher gets remapped IP addresses and these mean nothing
|
||||
inside the LAN, only make sense when used from the outside world]
|
||||
|
||||
Score.
|
||||
|
||||
Remap movement keys not implemented.
|
||||
|
||||
Allow game hoster to set network game options and have them visible to players
|
||||
who have joined the game.
|
||||
|
||||
Alternate gfx sets.
|
||||
|
||||
Better handling of 8 bit mode with limited palette.
|
||||
|
||||
Computer controlled things that can kill you.
|
||||
|
||||
Other bonus types that can be harmful, such as skull.
|
||||
|
||||
Internet play where everything is asynchronous, thus playable with a fixed
|
||||
latency. As it is now slaves send to master, then master sends back to
|
||||
slaves, and this data xfer must complete before the game can advance a step.
|
||||
For internet this would be intolerable. I've never tried though...
|
||||
|
||||
Better docs, online explanations, attract mode...
|
||||
|
||||
Single player with computer controlled figures that must be killed/avoided.
