Great game so far, but I should point out that the solar cells... seem kinda broken. They seem to be giving their energy per tick rather than per second, which means even on a modest world they fill up within 10 seconds.
It's a pretty decent game overall. At least, it kept me addicted until the end. It was extremely easy though, I never even bought a battery until I'd maxed everything else. Not a bad game for your first one, although mechanics wise I would say Motherlode wins. But they also have several games under their belt. Keep working on games. :)
