Do not leave any points from the start of the game. Since when u reach
a score of 20,000 u will get a another life. It means for every score
of 20000 multiples i.e. 20000, 40000, 60000, etc....u will get a new life.

Hint:
-----

In the sixth level dont take the trophy and try to
go through the door. Then turn right side go right
side you will reach the warp zone of level 8. Where
jetpack is also available for you.

Gameplay Mechanics:
-------------------
There's some sort of obscure background story, where you're going
through 'Clyde's Hideout.' Whoa...could this be Clyde, a.k.a. Shadow,
from FFVI?!? You never actually meet this mysterious individual, so
let's just assume it is, eh? Good.
DD features ten 'normal' levels and four bonus rooms. To leave
the level you're in (regular or bonus) you have to pick up a gold
trophy that'll be lying around somewhere in the level and then go
through the exit door. Leaving a level nets you two thousand points,
unless you're just entering a bonus area. K.
Left and right move you—wait for it—left and right (and down, if
you're flying). Up lets you jump. The Ctrl key activates your jetpack
(if you have one) to let you fly, and the Alt key fires your gun (if
you have one). And that's about it. Simple, eh?
A few other things: if you stand in front of a tree, you can
climb it by pressing up. If you're positioned properly, you'll
actually *climb;* if not you just sort of jump up and fall down once
you reach the top (the falling being slowed if you're 'on' the tree as
you're going down. You can also do this jumping thing on the stars
that appear in the sky in several places ('fly me to the moon...').
You can kill enemies by either shooting them (only one bullet
allowed onscreen at a time) or, if you're feeling reckless, crashing
head-on into them, which, naturally, kills you as well as them. And
you do not get points for irresponsible kamikaze tactics like this. So
take heed.
