This game, a minigame I would say, was made in two days for a czech competition at a *censored* forum. It won the first prize, which was ... nothing actually. The game might need some tweaking, but it's playable in the state that it is in right now. This was actually not a bad attempt at a game, I think.
The language, again, is unfortunatelly Czech only. Runs on Windows 7, or higher.
What do you do in this game? It is purely a survival interplanetary kind of thing. You collect "demence" as cash, you build defenses on planets. As you activate the key dialog with the king, the enemies start spawning. Ships arrive, they fly around and they spawn troopers. You can shoot them, or you can build defenses. I think there was never a thing such as a medkit implemented, so ... take care of your health, you will never recover what you lost.
