nice tactic to defeat very easily the last boss. take the time stop and the darkness energy charge ( DEN now ). when the boss appear freeze the time shotting al you can shot. after when the DEN is working start to push the boss out of the screen...this cause a litte damange to your ship because the boss can't shot if you are pushing it out the screen..when the DEN have recharged all the energy go down just a little, the minimum to hit the boss and not the free space XD. 3 or 4 action with this tactic and the boss is easily defeated. with a good upgraded ship the freezed time is sufficient to auto repair the healt losed in the push action. :)
Thanks, I'll try to add more :)
