Having just released the retro shoot'em up Laser Sky Zero, a prequel to the original game (itself recently relaunched), I give you the pixel art sprites drawn for the occasion:

• player ship, 7 enemies and 4 powerups, for a total of 12;
• 16x16, 3 colors per sprite (plus transparency), picked from the DB32 palette;
• monochrome versions included just for kicks; maybe someone wants to use them in AGD or something.

Enjoy, and I'd love to hear from you.
