Asteroid Hunter

This is my first completed project in a long while, well... it's still got a few iterations to go but it is now my secondary project as I work on another 2d project.  

I decided to publish this as is because it is now stable and all the modes I thought of are in it. However the next phase is up in the air, I can go rogue-lite, multiplayer, or some kind of survival rpg style... Maybe even some hybrid of that group.

Regardless this was fun to get this far and satisfying, I look forward to any feedback on bugs and such or just ideas to add to this project.

Controls ===
Rotation: "A", "D"
Forward/Backward: "W","S"
Booster: "Left Shift"
Return: Escape Key (This also cancels fullscreen).

Progression===
Getting higher high scores unlocks harder difficulties. The game tells you what you need to unlock the next difficulty/stage.

Features & Tips===
The power ups appear more in lower difficulties:
Red Heart heals you, Blue Star gives you a shield.
Red Rocket gives a 25% speed just on boost, Red munition gives 25% faster fire rate.
Green Rocket gives 25% longer boost, Green munition gives 10 second longer shot duration.

Debris on destruction drop power-ups.  If you already have a powerup or max health you can't pick up a power up but you can collide with them. Colliding in this way wont hurt you. You can use the debris and powerups as a kind of barrier against asteroids.
