Its only a weak AI till you hit the 80+ levels. Final fight is easier then many of the high tier battles, even without capital ships or the physics lab
I found the final fight to be easy. Immediately build the starport building super carrier behind your base, then build 6 autoguns in front with your remaining energy. Then sit back and enjoy the show.
First try. Killed the dragon(You NEED divine edge before you hit day 15), got max armor/weapon(Get a gold ticket ASAP!). Ran till day 21. Score:2879130

4)Any two of the above.
5)In under 10 minutes, in the basic rocket, and without radar

I think it's something with local storage settings in Chrome. Couple of people had the same problem / bad luck. Unfortunatelly I haven't seen that issue yet on my own eyes, and don't know the step by step solution for this problem.
