Space Warrior is a top down shooter game. It has tons of particle effects and runs at a smooth 60 fps.

This game will have four difficulty levels:
EASY
MEDIUM
HARD
INSANE

The controls are simple: Move your mouse to guide the player, and shoot by clicking.

It will also have multiple enemies, and bosses.
We also plan to make unlockable modes and challenges.
This game has some features that are inspired by Everyday Shooter, a not-so everyday shooter you can buy on the Playstation Network. Explosion chaining is one of those features. Blow up a certain type of enemy or object and it will create an explosion that when touched by another enemy will cause that enemy to explode the same way, so that when another enemy touches it, it will explode like that, and so on. Explosion Chains are a great way to rack up points, because enemies destroyed that way are worth more points. Although this feature is not in the trailer below, it will be in the demo we will release soon.

EDIT: This trailer is way outdated. The game is a LOT different now, and the demo is coming really soon. The shooting idea is the same, but now the game kind of makes sense. There is a space ship that has tons of cargo and space pirates try to steal everything on the ships way to the next planet. Your job is to stay with the ship and shoot the space pirates before they steal too much cargo. There will be challenges to beat, such as

get a x3 or more Explosion Chain while defending the ship
don't let any of the cargo be stolen by the pirates
Beat the level with more than 5,000 points

The challenges will come in sets of three. You unlock a harder set once you complete all of the challenges in the previous one unless you already unlocked all the sets.

space warrior sounnds like a cool game to me.
