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 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
amazing game would be nice for the "sandbox" to be infinite but otherwise it's a great game
I can't believe such a good game is free!
非常好玩 循序漸進地燒腦 我一個文組仔也玩的津津樂道 試著推薦給其他理組朋友玩 發現就算是會寫程式的朋友也無法秒解 所以不太會有基礎知識的差距 推薦給喜歡動手試試看、喜歡思考 或是喜歡用各種出人意料的方式解題的玩家 就算不是碼農相關科系也可以玩 同一道題有無數種解法 很有樂趣 (免費遊玩真的太佛——)
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.
