i've gotten to a point in my life where i'm playing games about tiny things that evolve into bigger things where i'm currently a amoeba flying through space with a tail, eyes and slime coming out of me! i'd say this is a good point in my life. at the lease it's better then the point in my life where i was laughing at swearing. and the point where i actually had fun other then the internet.
i got through the "this is sparta" thing with a space laser (no upgrades) spending the rest of my money on gunmen and i think i bought a couple of repairmen, i don't know, i also aimed for big groups of enemys
