July 2025

-- Primary Coding -- So when I was in primary school, my life goal was to be a game developer. Then one day we had a computing class where they had us using Scratch. Basic but cute programming software. At the time I thought “Great! I can get a head-start on learning to code!” By the end of that class, I absolutely despised coding. I thought it was the most tedious, long-winded work I’d ever done. And just like that, my I changed my life goals. Years go by and I occasionally see games from Zachtronics. I always think they looked too advanced for me. Not my scene. But Opus Magnum allured me, for some reason. So in this summer sale (2025), I decided “screw it. I can always refund it.” In the first two days I had Opus Magnum, I put over 12 hours into it. -- Alchemic Perfection -- Opus Magnum might be the best puzzle game I’ve ever played. The sensation of watching a doohickey you’ve made create alchemical formulas is hypnotising. Many times I just watched them go on and on, admiring what I’ve done. And the thing is, a lot of my machines weren’t even fully optimised! But Zachtronics have managed to make it satisfying no matter your skill level. By the end of the game I really felt like a mad alchemist. Going back through my older machines, I’d think “This is good… but it could be great.” -- A Betrayal Left Wanting -- The only detraction I have for Opus Magnum is its story. Spoilers from here. When I played through the first few chapters, I thought the main character was going to betray his House. Or just leave at the very least. But instead, the story instead builds a revenge plot, for these characters who I think weren’t given enough time for proper attachment. And so I ended up not being super invested in the rest of the story. I thought it would’ve been really interesting to have the MC leave his initial House. He was clearly frustrated with how ignorant they were, and how he wasn’t fulfilling his potential there. It would’ve coincided very well with the player’s view; you only see glimpses of them outside your alchemical work. So just like the MC, you don’t really care much about them. That could’ve led to some really interesting plot-beats, but at this point I’m writing fanfiction lol. -- Conclusion -- Opus Magnum is definitely worth a try, even if you’re only mildly interested. You may find yourself pulled in for good.

The experience: you build a shameful, jittering meatball of pistons and regret. And yet, you’re proud. You watch your creation spit out product after product, inefficiently but reliably, like a factory designed by a caffeinated octopus. Your friends share screenshots of their compact, elegant builds, and you respond with your 37-arm monstrosity held together by timing loops, divine mercy, and stubbornness. You name it “The Alchemajestic Horrorspindle” and defend its honor in Discord debates. But... that’s the point.The game doesn't want your machine to be perfect. It wants you to care about it. To iterate. To optimize. To tear it down and rebuild it three hours later because you found a way to shave off one cycle and you hate yourself just enough. 10/10 - still hating myself.

Zach heard people's cries and gave them a game that is slightly less torturous

March 2025

Grog see game with shiny colored beads and ticky tock wheels. Grog try to string shiny color beads in right shape, but Grog not smart and it make Grog head hurt. Grog solutions take too many cycles and look like Grog ass. Maybe if you smarter than Grog you like this game.

Have you wanted to do alchemy, but also play factorio at the same time? Well, this is a game for you. It has pretty good and challenging puzzles, the story is interesting - and as every zachatronics game, there is also a board game built in for when you need a break.
