SAYONARA++ is a retro-programming game. Tokyo holds the last remnants of human life. All our pilots are dead; you are our sole surviving AI. Commandeer a fleet of dormant mechas via an ancient backup protocol. Inject assembly code, optimize sparse memory, and achieve absolute annihilation. Never forget that The Core is observing you.
SAYONARA++ is a cold, uncompromising, low-level assembly programming environment. There are no high-level abstractions, no drag-and-drop blocks, no safety nets, no tutorials, and definitely no hand-holding.
To survive the 23 wards of Tokyo, you must:
- Manually type raw code line by line using strict retro terminal syntax.
- Press [F1] to read dense technical info and hardware specifications.
- Track clock cycles, jump labels, and volatile memory slots to orchestrate your mecha’s movement.
If you do not know how to think in assembly or untangle code errors, this system will lock you out, reject your input, and leave you stranded in a dead machine. This software is engineered EXCLUSIVELY for optimization masochists, hardcore programming purists, and low-level logic enthusiasts.
Built for minds hardwired for raw code and low-level logic.
Sayonara++ is a game we developed for the 2026 Steam Programming Fest. More updates to the game coming soon!
