currently it's a serversidesetting, if the demand is high enough, i might make the clients able to change it, or at least increase it (and announce it to brag about it :P)

the first version with difficulties will be released on sunday.

currently iam testing these difficultyfeatures:

as is (i hardly survive winter with her currently, and i have 2 year characters in DS RoG with all bosses beaten, so yeah :P)

every overlord reduces your max hp by 10
no more sanityauras on minions
wild zerglings will attack everything but other zerglings and overlords, making deaths more scary
similar to houndattacks, u will get regular zerglingattacks(to be nydusattacks in future updates)

max hunger 200 instead of 300
hungerrate 60% higher instead of just 30%
zerglingattacks more frequent and one right when u spawn

units cost 25 more hunger and also some health to spawn:
drone 40
zergling 10
overlord 60
i currently decided this healthcost to have no minimumhealthrequirement to spawn and it reduces your hp at most to 1, so u can save healingitems by spawning a lot of stuff at 1 hp, but it's risky
