(a few days later) Success! And yet... where's the followup Dinochrome Brigade game? (searching on internet) Should have known!
Okay, so level 1 is down. But what about levels 2-9? I hate to say it... okay, I don't hate it that much, but to me it feels like Gridrunner all over again. I use Gridrunner as the example because I saw an ad about 40 years ago for it that declared something about how it's an unbeatable game. Well, yeah!... if there's way too many enemies and you have a gun that's just not that powerful... oh! There's the ad right there at the bottom of the Atarimania (TM)(R)(C) page! Okay, I'll try level 9 with a maze density of 9... 5.
