For who is trying the impossible, some advices:
1 - look for the guides on youtube, there is some of them with different methodes.
2 - What they don't say that helps, when you are going out of the water, to tailslide, aproach the water in a horizontal position, if possible almost as horizontal as the water level. Even if when you fall from a great height you need to swim for a couple of seconds to do so, do it, it makes a lot of difference.
3 - take as much starslides and height when going to space, but don't go further tthan the planet with rings, or it gets difficult not to hit the bottom. Going twice might help. The first time, just stairslide all you can. The second, get high and fall directly.
4 - not hitting the bottom is a matter of practice. And you also need a little luck with the starslides, speacially the ones after the first small blue planet.
The game has really nice graphics, sounds and technical quality, but the rest is too bad. The enemies are so small, they fly so ramdonly, and the shoots are so slow that when the enemies are are away is mostly luck to hit them or not because of this factors. And when they are close, they are already hitting you hard. Besides, the story during battles and the fact they can fly above and under the screen also don't help. Too bad such a nice game has such a bad playability. The idea is really good, but needs some work.
Too much difference in the levels of the players.... Satan is overpowering, Noah is very weak. So the game isn't fun, it is or too difficult or too strong. Against Satan, you can't get close to him without he hitting you, because he is faster, and when you are away he just throws the superfire balls or the dog. Against Noah, don't do a thing, just hit him. Too bad for this, it is not a good game
Simply impossible on the higher levels. You can't defead an opponent that attacks faster than you, that their attack, when you defend, takes twice as much as energy than an attack from you that actually hit.
For all that, the game is too bad, needs to be make easier or at least the speacial attacks needs to be easier to use, or they are useless.
Well, somethings about the game are too bad. Sometimes the enemy soldiers just pass yours and they don't do anything, don't even shot. You order your soldiers to move and they don't, or your bazuka guy kill all your soldiers and none of the enemies. It is a good idea, but need a lot of improvements.
The definition of the badge should be changed, because so far as I noticed, the EMP is also an obstacle... once I only hit two EMP in the game, and didn't won the badge... just won it when I didn't hit anything.
Some bugs on the game make it bad... for example key detection, sometimes you press the key and the game don't get it. And it is a little hard sometimes to see the letters in a middle of a croud of ninjas attacking, you simply don't know what to type!
Needs to be better worked... for example, the elevator don't work, you can get it and the ball doesn't go along... some tools are horrible. But a nice game... has a lot of potential.
This game might seen childich, but if you take time playing it, you might enjoy it. It is quite hard, and you need a lot of practice to be able to score big points. Just because the game seens childich doesn't mean it can't be fun! And in this case, in my opinion, it really is.
