I didn't like this one. It's extremely similar to Opus Magnum, but with the molecule manipulation turned inside out in a way that makes the system much less flexible and interesting. While it's cool that they managed to engineer out the need for glyphs by just having bonding/unbonding occur as a side effect of shunting hydrogen atoms, this just makes it less interesting since you can make bonds anywhere and there's no fusion/transmutation

Every puzzle was easily solved by just slamming down precursors in basically the same shape as the output, dumping hydrogens onto any extra atoms, and fixing up any missing or extra bonds. There's still some room to optimize after you get your first solution as usual, but I wasn't interested due to the rigid and restrictive feel. There's technically not a single way to solve each puzzle, but there's usually one obvious decomposition into precursors and not much space freedom

The only moderately tough puzzle was the second to last one, it took three tries instead of one

I also didn't really like the stark design or the way it just throws you in with no tutorial. I'm not sure I fully understood the bond rules ... obviously each atom type has the max bonds specified and breaking double bonds / creating single bonds is preferred over breaking single bonds / creating double bonds, but I'm not sure what the order for creating single bonds is when multiple are possible

The main character's narration is really cringy. I understand that the minimalist aesthetic was chosen to immerse the player as being miserable and trapped in their "small Romanian apartment" and this is supposed to explain their edgy misanthropy, but it's just bad

There's no option to skip to a given instruction like in exapunks or opus magnum

There are glyphs for wasd, q, e, r, f, v, x, and c, but even though the ui shows there's a locked one for z, it's not available in any of the main puzzles. Maybe this is used in some of the bonus puzzles, but I don't really feel like playing the bonus puzzles or solitaire for this one.

If you like zachtronichs, this is good, because it is zachtronichs.
