I'd really like to see more of the screen... when I run to the other side of the boss level to avoid shots, I have no clue where the shot went! I end up running back into it anyway... D:
I did not read the PDA entries very closely & did not realize until I had 100% search that the survivor I assumed was a bug (she had a slightly different action when rescued, didn't have a name, and followed me everywhere) was actually my rescued daughter. Turns out the "FOUND" notification was #5 of 73. -_-
Best play method: work in a spiraling motion. Always go clockwise or counterclockwise, starting from just 1 square away from your home bubble. This will get you the easiest enemies at the very beginning and save the big, bad guys for the outer layers of your spiral. I worked toward the BFT series (rightmost upgrade every time) and beat the final boss at about the 5th layer of my spiral. Easy-peasy! ((Finding the extra baddies is still proving difficult, though...))
Ooh, sweet! Beat the game with all 4 methods at the same exact time and click "Keep Playing"... you will get all 4 endings without playing any further! :D
