Just found a drug, 'lightning', if you use it you have a 30% chance to die from a heart attack? for 1+ ap? for one turn? I wouldn't ever use that.
If you do have a heart attack, is there no chance to somehow survive?
I mean admittedly if you did survive you'd be unconcious and defenceless for quite a while and ripped apart by the local wildlife.
Multiplayer would probably be a little too much. As it is it is pretty laggy sometimes and plus this is the only game he's made [which is on kongregate anyway] can you imagine how hard it would be?
