Wow, this was fun.  I managed to research Machine Tier 7 before it finally crashed.  Spent probably 3-4 hours playing this.  Was getting slightly slower and slower as I played, so presumably ran into some limit at the end.  You can see the minimap of my factory at least from this screenshot after the crash here =).

Definitely ran into quite a few bugs - realized the belts would skip a space pretty early, but that kind of  became part of the design constraints of the gameplay at that point =).  The factories not being centered on their 2x2 area when they got bigger was a little hard to work with.  Worst was them growing in the build palette meant that after tier 4 I had no access to iron bars anymore (no way to place a new furnace as I could find no hotkey for it, and couldn't get to it on the palette anymore), but I managed to work around it.

I didn't like being forced to use the new, larger assemblers/sellers/etc.  I almost got hard-locked when I reached a new tech tier, and the seller was now super expensive compared to the previous tier, more expensive than I could afford, and I didn't have any seller placed down anywhere near my science pack production chain :D.  Managed to route things back to an old one without doing too much damage and earn enough for a new, high-tier seller.

The little units that produce higher-tier components without inputs were fantastic.  Price felt just about right (they're the only thing, besides that one seller, that I found myself saving up to buy), and they're very satisfying compared to "okay, now, let me double the size of this boring part of my factory" and let me focus on the new, exciting part.  I'm curious what other factory games you've played might have that as a concept (because I'd probably enjoy playing them), or if that was something novel?

Individual pixel art was nice, everything felt recognizable and pretty unique, even all of the components - I found myself able to just use the icons to recognize what I need to craft rather then needing to double-check the names, which was nice.  If only the tooltip tips on the assemblers also used those icons so I could tell at a glance which one I was lacking =).  Overall composition felt a little inconsistent, with things being scaled different sizes as they grow bugging me a bit.

Maybe interestingly, I never realized, until very late, that you could cross belts - since the underground was unlocked initially to solve that problem, I didn't even think to try until I did it accidentally (and at the point I figured it out, I was too scared of belts mixing due to bugs, I mostly avoided it :D).

Overall, really awesome work, I've enjoyed this one more than any other game in the jam by far =).

I like how you focused your efforts on creating interesting pipelines. It is similar to how shapez don’t have pressure, just casually browsing how to get from A to B. I think I would love a more puzzle approach than an incremental one for this game.

I encountered bugs: the underground belt sometimes moves items in the wrong direction, or some part of the pipeline breaks. Not sure about either, as it was hard to reproduce. Much of the player’s friction for me was how tedious it was to build, especially because every building doesn’t have an input, but has an output (which can be counterintuitive after other games from the genre).

Talk about being spot on for theme. And it even has a tutorial: very nice. Through mistakes that were entirely my own fault I managed to stop mid tutorial to try and restart doing things in the order it asked me to and it seems like maybe you have a persistent storage set up so that I can't get back to it? Is there an easy way to reset short of throwing away all of my itch cookies (which I'm not going to do!!)

I found the game concept fun, however, it felt really difficult to build stuff using the current controls, and it wasn't clear to how to progress past basic smelting and selling. The individual factory units also didn't feel very visually distinct, and I wasn't able to progress very far. I also think I encountered a bug with the assembler unit regarding sp1.

Ok, now this is my favorite game so far in the jam, I love factorio so this was an easy pick. I feel though that the calm and soothing soundscape contrasts a bit with the factory theme (I want the stresssss! lol), but that is just a matter of preference, I think this is a solid entry and I want to have more time to go back to this game after the jam ends.

Wow and I thought my game was complex! Very interesting game  - the animations were really well done, but the text a little less readable than I would like

I appriciated the tutorial, although it was a bit weird that there was an overlay covering the play area when I wanted to place things.

It's cool that the game save your progress, although it would be nice to reset the state - maybe I missed the option. Well done!
