Prototype
Differences
|
The left difficulty switch changes
between the space screen and the trench screen.
|
Only one Tie Fighter appears in
this version, and it will endlessly circle around shooting
fireballs at you. |
The Tie Fighter will stay on
the screen even if you switch to the trench screen. |
The fireballs only have one
size and do not appear to come out of the background. |
The fireballs cannot be shot or
avoided. |
The fireballs are green instead
of red or blue. |
If your shields drop to zero the next
hit will reset them to eight.
|
You can shoot, but
you can't actually hit anything since there is no
collision detection. |
Up and down actually move the
crosshairs up and down. This is the reverse of the
final version which corresponds to real flight controls
(up is down and down is up).
|
The stars are light green and
are much blockier than the final version |
The stars fall straight down
from top to bottom instead of coming from the middle and
going to the left and right. |
The
counters for tower points and number of towers left is
always displayed on the screen even thought he tower
screen is not present in this version. |
The crosshairs movement has
been slowed down a bit. |
The tower screen is missing. |
The walls of the trench are
green instead of blue. |
There are no barriers in the
trench. |
Neither the space screen or
trench screen have an end. |
There is no copyright message |
The game starts automatically. |
The score counter doesn't work. |
There are
no sounds or music. |
The color/B&W switch freezes everything on
screen. Fireballs will still move and damage you
however. |
The design of the cannons is different. |
