Space Shoot-em-up Asset 1 - Overdose 3

Here is my first "Horizontal Space Shooter" asset in pixel arts. Each tiles are based on a 16x16 pixels grid which allow several combination for space shooters video game in the pure style of old arcade games (R-Type, Darius, etc.)

The space ship seen in the captures, and the visual effects (flames, smoke and lights) are not included in this package that contain only tileset and background in PNG file format.

All assets here are totally free for commercial use, studies or editing. Credits are optional but appreciated.
