Enemies approaching you are most of times regular formations of spaceships.
You will encounter many double ways in the game. If you happen to find a dead end, remember your spaceship can go back.
Shops are at the end of levels but often at the middle of them as well.
Contact with foes damages you the same way enemy bullets do.
The C-marked bubbles add credits.
There are many upgrades available to your ship which makes you much more effective in fighting. You get such upgrades destroying certain flying objects or buying them at the shop.

Approaching the big surprise at the end of level 2
Voila! A huge spider queen appears.
Level 3 has a Star Wars like feel
The shop has all the nifty things a real pilot needs.
Some levels feature several narrow sections.
Temporarily protected by a shield.
Wait for the right moment to fly past those volcanoes.
A dead end, now I must put my spaceship in reverse.
The last part of the game has a mechanical feel to it.
Blasting away with massive laser beams.

The upgrade to fire backwards comes early and is very useful.
Graphics took a notoriously hit on quality in this port. Everything looks blue tinted.
On one side, the terrible snake-things that can tear a ship apart, the other's a dead end. Sadly, there's no easy way around here.
Those slugs on the walls must be taken care of before entering those tunnels.
Now with a missile power, doubling the firepower of the ship.
Enemies are also harder to spot, as the colour palette of the console is more limited.
I didn't do that well, eh?..
Those damn walls will shoot at you
