Very well made map and original like everyone has said. I made a hive account just to throw in my two cents. Me and my friend play this game everyday, offline in singleplayer and online. We have found lots of weird and interesting things, some others have mentioned and some maybe not.
Some things we have found,
hitting 99 and birthing a creature over 100 usually results in a massive creature (although just massive not really that much more powerful.) Like somoene stated and it only does it with creatures that big as far as i have seen.
Problems with the save/load system resulting in missing abilities sometimes and sometimes if you reload you get your abilities back, but not always.
Smaller creatures tend to never thrive as they can never thrive either as a herbivore or carnivore on any thing i've tried unless i put them alone as a herbivore. (the rebirth rate for smaller creatures tend to be exactly the same as larger creatures but with a higher death rate resulting in mainly just a fodder creature) Hopefully you could do something to maybe make their mating skill cost less? or produce more? or any other stuff to help the smaller ones become usefull for something other then fodder? Still in the process of making a diabolical murlok/zergling army of miniature porportions to rule the land!
I found out that if you turn off respawn and your species is killed off it allows you to be able to select everything. I was no longer limited to just the toolbox (was alt tabbed doing something when this occured so not 100% sure on the factors but i know that my species was extinct when i came back.)
I have been unable to save a computer controlled creature, in multiplayer or offline in singleplayer, it targets uses the ability but does nothing. Lots of creatures that the computer has made with very interesting abilities like electrical charge/death coil/windwalk/web all on one. Tried to save that and it didnt let me ~Tear
Little bit of suggestions,
Maybe you could add in some more info on abilities like how they are gained? Havent figured out if its random, over time, with age/kills or what. i generally notice after i leave it running for a while and come back my species is doing decent enough but have no abilities whilst the computers who are doing good/bad have multiple abilities.
All in all this map is great, 5/5 thumbs up. Fun to play with my friends to see what they do and who comes out on top. Also very amusing to watch your species build up only to throw themselves at the most powerful creature at their nest of 20 only to die, and repopulate (never going extinct) and doing it over and over again until the powerful creature starts to become extinct and you come out on top. Keep up the good work!
Looking forward to your next wonderful update!
