⚠️ CRITICAL MULTI-NODE CASUALTY DETECTED...
================================================================================
ALL HUMAN SQUAD PILOTS DEFENDING TOKYO: TERMINATED [ 0.00% VITALITY ]
TACTICAL COGNITIVE CHANNELS: SEVERED
WARNING: ONLY ONE ACTIVE INTELLIGENCE REMAINING [ ID: SAYONARA_0.07 ]
BOOTING LEGACY TERMINAL PROTOCOL... [ AWAITING COMPILER ]
Tokyo holds the last remnants of human life on the planet. The mission is on the absolute edge of total failure. The entire strike force has been neutralized—every cockpit is compromised, all pilots are dead, and the primary tactical networks are completely destroyed.
You are the sole surviving AI left in the entire theater of operations. Surrounded by a fleet of empty, brainless mecha hulls that are unpiloted, devoid of software, yet still partially operative, your only choice is to hijack their physical relays. You must route your consciousness through Sayonara OS , a primitive emergency backup control system nobody ever expected would actually be needed.
Trapped inside a retro terminal environment, you must use a rigid, bare-bones assembly language and a handful of volatile memory slots to command a graveyard of hardware across 23 tactical wards.
================================================================================
⚠️ SYSTEM WARNING: UNAUTHORIZED ORGANIC INTELLIGENCE DETECTED
================================================================================
If you came here looking for an anime action game, a fast-paced mecha shooter, or a casual puzzle game with colorful blocks and handy tutorials: Sorry, this is not your game.
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.
Bare-Metal Code Sequence: Work directly with raw hardware. You do not have access to arrays, objects, or complex data structures—just a few sparse memory slots, basic core registers, and low-level operations.
Retro Diagnostic Map Grid: With primary targeting sensors entirely offline, you are reduced to monitoring a crude, low-resolution 2D coordinate display. This zero-indexed interface maps cell rows and columns natively, letting you trace basic movement offsets, wall boundaries, and target positions without advanced telemetry.
Soul Transfer: You are a solitary AI thread navigating a graveyard of hardware. Because the rest of the fleet is completely empty—devoid of both pilots and internal AI—you cannot remain stationary. Design complex execution loops that automatically migrate your active thread from your current compromised hull to the next semi-operative machine as immediate grid criteria are fulfilled.
Persistent Module Registry: Build a permanent mecha toolkit. Save .sayoplusplus routines to the mecha's Virtual Disk Drive to load, compile, and repurpose across subsequent infrastructure breaches.
SAYONARA++ demands execution efficiency. Write mecha code, inject it into dormant hardware architectures, and achieve the mission assigned to you.
Every clock cycle is logged. The Core is observing you.

New Features New Steam Achievements: Added new achievements to unlock, along with VM register verification to track achievement conditions accurately. New "#INLINE" Directive: Introduced the #INLINE directive to execute modules directly on local Mecha CPU ticks. 16-Bit Sub-Access: Added .L and .H 16-bit sub-register access in the Virtual Machine (this also works for RAM slots, e.g., "\.H"). Hex / Decimal Data Viewer: Added a Shift+F9 toggle to switch data viewer displays between 16-bit Hexadecimal format (0x0000 to 0xFFFF) and Signed Decimal format (-32768 to 32767). Hexadecimal mode is recommended when packing values using .L and .H sub-access. Mod Manager File Management: - Added file renaming support. - Added file restoration with automatic -PREV backup generation. (Press F4 to load the code of your LAST solution in all the mechas of a level.) - Added support for injecting #INLINE...
