> Even by the 4th level there are too many enemies to track. I love this game. The flashing colors are very stimulating, but the beauty of this game is that it's about judging tradeoffs in a constantly changing environment. Yes, starting at the 4th wave there are too many enemies to track. The zen of the game is this: you will lose some lives every wave after a certain point. But the game is generous and you will earn bonus lives every X points. The wandering humans in the game give you 5000 points each, but only after you save 5 in a row. You can rack up extra lives pretty quickly if you can waver through the robots and obstacles and hit 5+ in a row. So you have always think - will this path through the changing morass enable me to save a large enough chain of wandering humans to gain more lives than I'll lose? You have to constantly make "business decisions" to keep your profits (total lives) ahead of a fatal loss (your last life). Not that I can get past wave 14 or 15 though.
