I'm curious how some people can think something is "impossible" even when so many other people can do it. Slow and steady, with lots of reactors and speed upgrades does it, no problem.
@almafeta: not exactly true. clicking upgrade like that doesn't give the second upgrade for free, but it does skip building the first upgrade so it still saves on time
Found a bug. At seemingly random times, after buying a menu upgrade (like the background or copyright), my entire ship gets deleted. If you spend all your cash and this happens, you can't kill anything and get stuck, since you can't earn cash and have nothing to sell.
Needs a do-over. If the interfaces were better it would be more fun. Also, three clients in a row with a budget of under 20 coins pretty much kills the game.
Like others, I qualify for at least two of the achievements and the challenge, but the game isn't reporting my stats correctly. I tried reloading them, but it didn't work.
