As an alternative to the thatguyyaknow method of building lots of dart monkeys, trying using the glitch firestorm77 found and place ONE hypersonic tack tower within the first loop. That should take care of everything for you.
Doubt it's an issue with the game, but every time I revisit it to continue, all of my spudniks, plants, and stuff are missing from the Planet Looker, everything I've discovered about the orbiting mass is gone, and the watts per second is significantly lower (I think it's what I would generate with only potatoes and solar cells). I think this is something about how I can't save a game for some reason, though it originally worked.
Aside from this, it's a great game with good graphics and a nice storyline. Looking forward to seeing the full version!
