PIXELTokyo 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
SAYONARA++ is out on Steam with a 10% launch discount. It is a programming game dressed as a mecha story, and its store page opens by telling you who should not buy it.
You write assembly to pilot the mecha
The premise is that you are routing your consciousness through Sayonara OS, an emergency backup system nobody expected to need. The mecha around you are intact but empty — no pilots, no software. Commanding them means writing code in a deliberately bare-bones assembly language with a handful of volatile memory slots, then injecting it into dormant hardware.
Twenty-three tactical wards
Missions are structured across 23 wards, each a puzzle in resource-constrained programming rather than a combat encounter. The store page notes that every clock cycle is logged, which suggests efficiency is scored rather than merely permitted.
The developer tells you to leave
Halfway down the Steam description is a blunt warning: if you came for an anime action game, a mecha shooter, or a casual puzzler with colourful blocks and tutorials, this is not your game. That is unusual honesty for a store page, and a useful filter — this sits closer to Zachtronics than to a giant-robot power fantasy.
Who it is actually for
Anyone who has enjoyed optimising a solution more than finding one. The retro terminal framing and the constraint of a minimal instruction set are the appeal, not the setting. If shaving instructions off a working program sounds like a reward rather than a chore, it is worth a look.
What it costs
There is a 10% launch discount on the Steam listing at the time of writing. Check the store page for the current figure, as launch pricing on small releases moves quickly.
The store page filters its own audience
It is unusual for a developer to spend a paragraph telling people not to buy their game. SAYONARA++ does exactly that — no anime action, no mecha shooter, no colourful blocks and tutorials.
That is worth more than any tag. A programming game that reaches people expecting a robot shooter generates refunds and bad reviews; being blunt costs some sales and saves the rest.
Where it sits
The obvious comparison is Zachtronics — TIS-100, Shenzhen I/O — where the fun is optimising a working solution rather than finding one. Logging every clock cycle points the same way.
If you have never enjoyed that, the mecha setting will not change your mind. If you have, this is a small, cheap entry in a genre that does not get many new ones.
