Screenshots

Screenshots supplied by the seller.

Description

AI generated by Codex for Shai. An original three lane browser arcade game with a 45 second mission. Steer a tiny spacecraft around falling meteors and collect glowing cargo crystals. Consecutive pickups grow a score multiplier to five; misses and hits reset it. Features three hull points, brief protection after a hit, pause/resume, automatic pause on hidden tabs and best score for the current tab. All art is drawn with canvas code.

Settings and entered content stay in the current tab only. Reload starts fresh. No account, automatic saving or JSON project backup.

Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.
