Nice to see you like colony, i love that game, better, loved, it had better times, now, most of the people are just cheating -.-'
That idea you had is good, but you're making the game into a 99% Call Of Duty, and the only coder they have is Ido, i like the script, it's long but it gives the idea of the game, i agree with u, graphics are awesome!
I think if the script could have a bit more of improvement, maybe a bit longer, not only 15 levels, a bit more, like >50, that script would be used to make a good 3D fps game, i dont remember who write the script, its 5* for a flash game, but i say it again, you wont make loads of money by producing flash games, so, the best thing you could do, with time, gather a small team of like 10 coders, 5 concept artists and some more that you may need and upgrade Echoes from a Flash game to a 3D one, but spreading the game wouldnt be easy, maybe starting a litle dema like nightmare house (never played... slow computer) and then, if the croud likes, move on to 3D game, maybe with some company help like THQ or something... Its up to you and your fellas, just giving my opinion , a bit reckless (A LOTTTT) but there are risks that need to be taken in life, and i see you got talent for that!
Who could know that Bill Gates, a simple kid, would create the biggest company in the world?
