the game is great nothing bad expect bugs but they will be fixed so LET THE FACTORY GROW!!!

This is a nuanced recommend. The game is kind of ♥♥♥♥♥♥♥. It's exactly what it says on the tin. It's FAR, FAR better than other factory-styled incrementals you might play- this is right up in the Factorio/Dyson genre, with some severe caveats.

First up, expect some bugs and lack of polish. Random slug text instead of friendly names ("oreCopper" instead of "Copper Ore") in various UI elements. Map connections being invisible until you switch tabs in and out. The challenge interface straight-up doesn't even have labels describing what the numbers MEAN until you make an irreversible (for the run) decision. Font design is awkward, with some text being too large and some being too small. Significant bugs around even being able to access your UI tabs. (Try not to spend ALL of your prestige points, and always leave at least one unspent, to help but not eliminate this issue.) The map mode, in particular, needs some coloring/styling to differentiate between node types/sizes.

As an incremental dev myself, all of that is forgivable... but perhaps not at this price point.

The underlying game is exactly what it sounds like on the tin, and it's delightful. The dev made a clever decision to make every recipe take a constant "1 tick" time, which really reduces the amount of mental division you have to do. The method of turning a factory game like Factorio (and it is, basically, Factorio, down to the science and circuit recipes) into an incremental by production challenges is clever and more fun than I expected.

But it also may be extremely frustrating for veteran factory gamers. It has a reasonably robust blueprinting system, but because of the way that the prestige upgrades work, your blueprints will be CONSTANTLY obsoleted. The blueprints carry over past prestige, but they're practically guaranteed to be suboptimal, and you can't even overbuild them in anticipation. For that matter, when it comes to node ("parcel") capacity, using a blueprint actually creates nodes using the old capacity at the time of blueprinting, ignoring any upgrades to capacity you earned since saving the bp. That means you can't even "tweak" the blueprint after pasting to utilize the new free space- you're forced to make a new blueprint from scratch, doing all the mental math involved.

The upgrade system is also extremely interconnected, which makes them powerful, but also difficult to utilize. You rubber=band between "not producing enough within your space" and "making far more than you can actually transmit to consumers." It all works out once you have more upgrades, but in the meantime means that your upgrades aren't actually useful unless they're spread evenly across five different trees. And because it's a tree, you actually CAN'T upgrade them uniformly, so you will have to swallow this unevenness.

These two quirks, combined, mean that optimizing is a fool's errand. You'll often (always?) be in a position where you're under-utilizing either production capacity, or logistics throughput, or probably both. The numbers change too much, too often, with each upgrade, in effectively random proportions, for it to be worth the mental overhead of trying to Helmod anything at all after the first few prestige cycles.

It gets a Yes from me anyway, because these frustrations are more because I'm instinctively trying to play it like a normal factory game, and not like an incremental. As an incremental, this succeeds wildly- every upgrade is powerful, if you are willing to redesign your factory for it. The prestige challenge mechanic encourages you to rethink the goal of your factory on each prestige cycle. The baseline node limits are generous, and prestige cycles are reasonably short at an hour or two. Though it's frustrating that blueprints have extremely limited shelf life, you also have a lot to do, chasing bottlenecks and remaking production lines.

Just don't try to optimize your production lines- that way lies madness. Instead, accept that every cycle is going to make some things better, some things worse, and embrace the toil of rapidly redesigning endlessly.
