that was a very fun game to play! I really didn't felt i was playing a gstudio game at all.. I wonder why you gave up on it.. you could have made a custom tool for your multiplayer needs i guess(but yeah, i wouldn't use gstudio's one either)
i managed to finish it too.. the ai being too hard was the main reason i kept playing it... and i also had to learn how much resources each unit needed cause it wouldn't display anywhere..
i had to build two water pumps very fast so i can start producing those raider guys.. 2 raiders and your main dude are enough to repel the first attack.. and then after the second attack, you can build that oil pump and it gets pretty easy after that.. Reminded me a bit of Warcraft's II ai for some reason.. it was a nightmare to repel 7 of them in Hard for the first 10 minutes. but if you did, they'd start acting a bit stupid since things aren't too straightforward after some point, and that's where Human's intuition comes in:)
Anyway, well done. This is one of the few A6 games that i actually played and had fun with, so that must mean something..
Cheers,
