Hello !
..sorry for my bad English...

I am a programmer from the Czech Republic. I have programmed amazing games such as:
- ZdendaZuma I.
- ZdendaZuma II. (with 10 datadisks)
- Pacman labyrinth
- Space invaders battle
- Dark City Road
- Greedy bat
- Tetris T
- Planet Rescue Mission
- Ufon
- Ninja-help-icopter
- Robbery
- Firefighter Tobik I.
- Firefighter Tobik II.
- Multijoy roulette for 17-players
- Bombeeno
- Robot and Minion
- etc...
I confirm that I wrote all these games by myself, every one byte, in pure assembler :)

===== Defense Horizon
============================

As my last games like "PLANET RESCUE MISSION", "DARK CITY ROAD", "FIRE FIGHTER TOBIK II.", ... were quite difficult to finish i decided to write a game that is very relaxing and not difficult at all :)

The BOSS PLANET DESTROYER is approaching the earth and only you can save it by fighting him.
Unfortunately, for this fight you need to get a tuned hovercraft, but you only have a normal, your own, home-built one.
So you take the untuned hovercraft and set off on a journey where you will gradually tune the hovercraft by collecting parts.

You have to fly through a corridor where there are parts, holes and speed bumps.
Holes and speed bumps will take your energy.

But if you get 30 components in every level, you'll tune the hovercraft.

If you press the joy-button in the corridor, there will be a temporary disintegration of the aircraft mass, so you don't mind the bombs and the speed bumps, but of course you can't collect the objects either.

The components are different in each level.
In the first level, you collect screws that are needed for tuning the hovercraft, in the second you collect doom-cards, next you collect dollars for buying new components, then screwdrivers for screwing the screws, next bottles with water and finally bullets for shooting.
All objects will help you improve the tuning of your hovercraft.

When the tuning is at 100%, you will go to fight the boss.
