✦ AI summary

MOLEK-SYNTEZ is a minimalist puzzle game where you control waldos through a graphical language to synthesize molecules, offering a programming-like experience with leaderboards based on cycle efficiency and command optimization. Players praise the satisfying automation mechanics and chemistry-focused puzzle design, though some note the game becomes easier once you grasp the core mechanics and that it lacks narrative depth.

Let's make Ibuprofen together. Speaking seriously, I really appreciated the game, I'd like to point out a couple of things: - The game isn't a programming puzzle, in the sense that you don't write code. However, you control waldos through a graphical language (each symbol represents a rotation, translation, addition or subtraction of an electron, etc.); each level is made up solely of the space where to insert commands and the prompt, and there are leaderboards based on cycle efficiency, the number of commands, or molecules used. In other words, even if it isn't one formally, the approach is actually very similar to a true programming game. - The game is even more minimalist than TIS-100; there, at least there was a PDF explaining the language, whereas here you open the first level and it's hard just to figure out how to interact with the game UI. Once you absorb the mechanics, however, I have to say it's quite easy. Or rather, the game offers far more tools than are truly necessary to complete individual levels—for instance, each waldo can execute at most 20 commands, but often half of that is enough, and I beat practically all the levels while ignoring the rotation commands. I…

I don't know if I'm a weirdo for synthesizing every molecule in the game and not winning a single game of solitaire (what?). Maybe I'm an ascetic. There were some unhappy moments. But it was worth it. I think.

Another Zachatronics game down. Even now, I am dreading the time when I finish them all. Amazing, if story poor (though what is there is intriguing). Bit of a shame how it becomes easy to deconstruct puzzles.
