I've been playing the game a bit more, and have a couple of observations.
- The game looks a lot better on a CRT. If you have one around, I'd definitely recommend trying it. You can play at lower resolutions with no scaling artifacts- all the lines are very visible and completely smooth.
- The endgame seems to be easier and a lot less varied than the beginning, because once the drop ship is destroyed there are fewer enemy varieties, and production declines as you reclaim nodes. This isn't necessarily bad on an ecosystem level, but it seems a bit awkward if you just look at the moment to moment action within the game.
Everything looks better on a CRT; I can't understand playing games on an LCD when CRTs are cheaper and crisper. The only drawback is their massive weight and size, but we didn't seem to mind it so much when they were the only things available, so I think that's a case of getting used to something else.
Anyway: vectorLocust! I tried it today finally (shame I tried it so late, I'm a big fan of jph's games). It reminded me of one of your other games which I forget the name of, but it was in GM and was also 3D perspective.
I couldn't figure out how to place turrets in this game, though. So I feel I'm missing something. I pressed '5' but that doesn't seem to do it? But just moving around and shooting enemies is fun. Although I miss the score feature, or something to keep track of progress. Without score there isn't as much motivation to play it over and over (to beat your old score by surviving as long as possible).
