ABI-DOS: The Ultimate Automation Puzzle Challenge.
In ABI-DOS, you build circuits to manipulate and guide UBITS (colored digital blocks) toward specific goals based on the given documentation. By strategically placing wires and instruction blocks on a microchip, you manipulate inputs to achieve desired outputs—whether it’s fixing corrupted files, recovering damaged .png images, or simulating particle trajectories. ABI-DOS challenges you to meet strict specifications through inventive problem-solving.

No programming experience is required, as everything is explained in-game. The focus is on assembling logical solutions within space and operational constraints rather than on real-world programming concepts.
The puzzles are challenging and offer no predetermined solutions, allowing for multiple approaches. Each level starts with a blank canvas, giving you the freedom to create your own unique solution from scratch.
You are encouraged to optimize your algorithms, fostering creative exploration and friendly competition as you compare solutions with friends and on global leaderboards.

With over 50 puzzles and more than 50 hours of gameplay, ABI-DOS offers extensive content for players to delve into.
The work is overseen by the system's Admin, a mysterious figure who is not what he seems. Set in a retro-punk world, this enigmatic presence adds an extra layer of intrigue as you uncover the deeper mysteries of the system.
Drawing inspiration from Zach-like games, ABI-DOS pays homage to its predecessors while offering a fresh perspective on the assembly puzzle genre.

Overwhelming stress reaction when trying to start level 2 :D this is what you get from getting older and being recently near burnout. Maybe 10, 20, 30 years ago I would have loved this game, and this genre. This is not for me at the moment, but I still give thumbs up, for all the past "mes" who have the working memory and cognitive abilities strong enough to handle all the information flood :D
A fantastic Zach-like (not a Zach-clone) with interesting new mechanics where you build integrated circuits from parts, rather than adding code to parts that are provided. There's very little hand-holding, which I appreciate. The docs, however, are poorly written and confusing, only making sense after I've figured out how something works by trial-and-error. Needs a better technical writer to redo them. 4/5

This game was [i]awesome![/i] The learning curve was a little steep, but once [strike]you get a grasp on what to do[/strike] the game gets its grasp on you, the learning just continues up through the end of the game. Going back and figuring out some of the challenge modes helped unlock my brain to figure out the later puzzles. The instructions are sometimes a little unclear, but you can usually figure out what to do by analyzing the output. I'm proud to say I beat the game, only looking up three puzzles (in the middle, funny enough. I just needed help to get over a learning hurdle. I got all the ones at the end by myself though!) I wound up designing some of the solutions in my head after a break, either trying to fall asleep or on a long walk, then building them in the game once I could get to the computer. You know the game is good when it keeps the back burners of my brain working! Hugely recommend, especially for its price of free. If you're a fan of Zachtronic games, you will love this.
I can't believe such a good game is free!
Inconsistent logic or impenetrable explanations. Sensors don't work in a way that I can understand from the description or experimentation.
amazing game would be nice for the "sandbox" to be infinite but otherwise it's a great game
This game has potential but the tutorial is horrible. it's very hard to understand stuff and even when you manage to find a solution it doesn't feel natural
I enjoyed the first eight levels, but upon the introduction of, one of the triggerable icons fundamentally did not work the way the game describes in the tool tip. I enjoy difficulty, but I have no interest in a system in which I cannot trust the game to accurately communicate the tools of the puzzle.

Extremely poorly designed Zach-like that just doesn't feel good and isn't fun. Tutorial levels are bad, tools are janky, mechanics are arbitrary and don't lead to interesting design. Skip it.
