It's funny how all the idiots assume the "try again" button is broken, do you really think the author accidentally made the game remember everything you did, and then accidentally made it play back when you push the button? I wish my programming mistakes would magically turn into a replay feature.

I have no idea why everyone loves this game so much, maybe it`s the pretty graphics and music.
The computer player has infinite money, and always evolves at about the same time you do, and the base defenses are very powerful; so the balance of power just swings back and forth the whole game until you get the mega turrets at the end.
This game reminds me of rock-paper-scissors, except both you and the computer can only choose rock.
