This game is awesome, but It need an in game currency, not everything based of the coins + Npc shops where npcs could sell, pots, for example, and then the market place where players can trade things among themselves,
When you're at the last stage of evolvement, keep sending units out until you got 4 ion cannons, then don't send anymore units out and let the ion cannons take out all the enemies until u got 300k. Then build 2 super soldiers, satellite blast the field to clear any enemies, and u win.
OMG I finally did it! And i got way over 3,000,000 feet....Lets see if anyone can me beat at 4440207 feet. I kept getting ammo refills with the golden gun, but then i ran out of ammo and started useing my 20 nukes, but nukes didnt make me go too fast, so then i hit stupid floating spikes....Darn spikes...could have gotten 5 mil feet
