What the developers have to say:

Why Early Access?

“Mnemonimov already includes the core features needed to write and debug assembly programs, but there's still room for improvement. Early Access provides a way to gather feedback from the community and understand what adjustments and/or additions would best complete the experience.”

Approximately how long will this game be in Early Access?

“About a year.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to include Steam Workshop integration and additional QoL features for programming and debugging.”

What is the current state of the Early Access version?

“Mnemonimov currently includes all the features listed in the "About This Game" section. Players can already write, run, and debug programs in assembly, although the experience might be a little rough around the edges.”

Will the game be priced differently during and after Early Access?

“There are no plans for a price change after the full release.”

How are you planning on involving the Community in your development process?

“Feedback and suggestions will be collected through the Discord server and Steam forums.”

About This Game

About the Fantasy Console

Mnemonimov (pronounced as ne-mo-ni-move) is a programming sandbox that recreates the experience of developing games for early consoles. Instead of writing high-level code and rendering colorful graphics, you'll be working with low-level concepts, writing instructions in assembly and rendering to a monochrome screen.

Specs and Features

32-bit register-based virtual machine with a bespoke assembly language.
Mixed-ISA design with RISC-style explicit memory access and a rich instruction set for development convenience, including floating-point operations.
Support for labels, constants, and data directives.
Integrated code editor with syntax highlighting and detailed error reporting.
Debugger with step-by-step execution, breakpoints, and the ability to inspect registers and memory.
Built-in command-line interface for managing projects and configuring settings.
4-bit monochrome display with 320×240 resolution at 60 Hz.

System calls for polling user input, drawing to the screen, printing to the terminal, and more.

Important Notes

Mnemonimov is not a learning tool. It will not teach you programming logic, assembly, or game development. There are no tutorials, levels, guides, or hints. Note that the included documentation is strictly technical, describing the assembly language and the virtual machine behavior, not how to learn programming.

Mnemonimov is focused entirely on programming and debugging. It does not include (and will never include) a sprite editor, sound editor, map editor, or any kind of asset creation tool.
