- How to play - Credits will be down. Move your mouse and hold to shoot. Shoot with the rocket, the shooting sound is not so loud. The aliens get shot after under 1-2 second(s) while touching a laser. The score increases by 5. Please let me know if you find any glitches. [down for credits] - Credits - The alien picture is the alien emoji. All code and scripts by me. My idea of aliens + space. And, shooting sound by myself. The music/song is generated by my Gemini. I made, and edited my thumbnail.
