Stage's Comments

Stage 1

When I die for the third time, I active the Bomb and getting 10.000 points with each Dogs in this stage. I only need 20000 points to earn an Extra Life.

Stage 2

At this stage, the Glitch doesn't work, then, I need the minimum Score 79290 points and the max 79999 at the end (the Boss when defeat using the Laser weapon, give me 10000 points and the bonus, more 10000). If I walk on the mines, I get 500 points in each, then, I abuses from this.

Note: ...it's calculate for the 4th Stage.

Stage 3

With the right score, this stage is very easy.

Stage 4

The Scooter-Robots are very hard to destroy with any weapon (except the Crash-Bomb), then, I manipulate an Crash-Bomb as a item at the stage's begin. I've started the stage with 90969 points, each Scooter-Robots gives me 7035 points, the next Extra Life comes with 140000 points, therefore, I 'only' need 49031 points.

7 * 7035 = 49245. =O

Note: Scooter-Robots are not defeated only by the power of Bomb in Hard Mode.

Stage 5

I've started this Stage with 150184 points, the next Extra Life will come with 200000 points. As in the 2nd Stage, each Power-Holder if destroyed without any enemy leaving from within, gives me 2000 points, the Boss when defeated with the Laser gives me 10000 points and the Bonus, more 10000 points, therefore, more 30000 points in this Stage again. But the only weapon that I have are the Crash-Bomb, and if used in the Power-Holders in the wrong moment, I earn a LOT points.

The Boss when defeated with Crash-Bomb, will also give me a LOT points, then, to get rid of that, I manipulate a Laser weapon in the last Power-Holder.

Final Stage

I've started the last Stage with 196673 points, however, without Bomb yet. The own Stage gives me soon this Bomb in his beginning, then, I catch her, then, I activate and I got killed by the Alien.
