Arrow keys to move, space bar to shoot. Dodge the enemies and the bullets they shoot.
Score will be submitted after defeat. The score recorded is actually highest number of kills in a single play-through rather than in-game score due to the scale of these two measures being relatively equal. To see the new score on the high score menu you may have to refresh the page.
Other things to keep in mind:
(For the purposes of bugs not being features, feel free to expand upon these ahem ?excuses? further for your own game-play enjoyment)
Getting your thruster too close to an enemy or projectile will expose you to too much reflected heat and will in turn damage you equally as much as collision itself.
Enemies(and yes, (mini)bosses) take damage from collision, feel free to exploit this when given certain abilities?
Choosing to skip inclusion of a start screen will help to bring the true adrenaline rush of being thrown into the heat of battle to the player and certainly wasn?t just left out >.>
I hope that anyone who does give this a try finds at least a little fun to be had, and thanks for playing!
