Carina chases Avior to an unknown planet, only to find herself pursued by the Hunters as well.
Arrow Keys - Move / Aim
Z - Shoot
X - Jump
C - Change Weapons (when available)
Spacebar - Pause / Open Map
You can also use WASD to move and JKL to shoot/jump/change weapons.
On some browsers/keyboards you may run into issues with too many keys being pressed at once, nothing I can do about that.
If keys appear to stick after being pressed, that's a browser issue.
If you have a PC Gamepad, I highly recommend using the Joy2Key Software. You can download it here.
Progress through the stage is saved automatically at every major checkpoint. If you have to leave and come back, your progress will still be there.
Be sure to check out the instruction manual!
