Fun parts of the game: You solve logical puzzles while learning how the computers work. The game is very rewarding. In addition to main game goal (create a CPU) you can add competition and try to create the elements of the CPU using as few logical gates as possible. Frustrating parts of the game: As elements that you need to build get more complex, their descriptions become more and more vague. Sometimes it's very hard to understand what it is required from you. My advice would be just start implementing small things that you do understand and continue as it goes. Most of the times, after you get your working solution, you will wonder on simplicity of it (especially with RAM, DECODER and CPU itself). Also sometimes you may realise that you had to put a MUX somewhere, or there was some more optimal way to solve the element, and now you need to rewire 5 or more contacts, which is not very convenient in the editor. If you made a tiny mistake and there's no issue in compatibility of the buses, the debugging becomes hell.

Fun little puzzle game. A little annoyed that the high scores have been set at unattainable scores by cheaters.

Learn logic gates and computer engineering in a fun retro way.

Actual time spent playing up until this review: ~7h (the rest were card farming and breaks I took without closing it) Other reviewers pointed out the availability of similar premise games but with GUI. This goes for the more stylistic approach, with bare minimal controls and simulation of an old OS. I really enjoyed my time with it, except a bit on pre-last puzzle was confusing. The good thing is, as you probably already know, it is actually applicable logic design and not some puzzles created just for the player. I suspect they might have wanted to make an expansion of sorts, or maybe a dlc, or just update with more tasks, but never got to it. Game is still good, grab it during a discount if you vibe with the style and idea behind it.

tl;dr If you enjoy games where you have to design or engineer things (e.g. automation games, zachtronics games, programming games, etc), this game may interest you. Details In MHRD your goal is to design computer hardware with something called a Hardware Description Language (HDL for short). If you don't know what that is or have never used one, the game contains a short tutorial and documentation that explains how to use it. This game's HDL is very simple compared to real-life HDLs like Verilog, so if you've written an HDL before, it may feel like you're taking a very abridged course on undergraduate CPU design. :) Overall, it's not a very long game, but it probably will take you a few hours to get through it. I've played through the game 3 or 4 times now. If you're like me and you really enjoyed designing hardware with FPGAs but don't have time to do it anymore, I'd recommend trying out this game.
