Here's the shooter I've been working on for a while, hope ya enjoy it.
Mouse/Arrow Keys: Movement
Z/Click: Main Weapon: Fast but weak.
X/Double-Click: Sub Weapon: Powerful but charges slowly.
C/Space: Bomb: Clears the screen.
Shift: Focus: Slows down your movement and shows hitbox.
If the game runs slowly, turn off the graphics stuff in the options.
Also, if you experience any problems with the keys sticking, just use mouse controls instead.
