First off I would like to say that I love the premise of this game. Factorio is one of my favourite games so seeing its mechanics in a game with this theme is a dream. Seeing the screenshots shows me there a really nice endgame.
However, there are some problems with the game which I hope get some sort of fix because I'm sure this game will be great once they're addressed.
The biggest addition that's needed is snapping conveyors. Consider this:
This was my third attempt at trying to align the conveyors to the funnel. Even now I cannot tell why the bottom conveyor works and the top doesn't. There are not even any indicators to show where they would align as far as I can see. There desperately needs to be snapping if a factory is going to reach even half the scale of the factories in your screenshots. Also it would be good if we could place conveyors on while there is an item in that space so that we don't have ot pause automation to add belts. Personally, I'm going to stay off the game until snap or some alternative is added.
The UI changing size as we zoom in and out is pretty bad as well. Also in my opinion the font is quite difficult to read. Those two in combination especially managed to give me a headache
Now for smaller changes. When clicking on an item to check its recipe, it would be nice to be able to see the recipe of one of its ingredients that we haven't crafted yet. Currently we have to go through one of the items we have crafted and hope it leads to the recipe of the ingredient we are looking for.
Being able to click the dialogue box to continue the conversation rather than clicking the arrow and question mark (I'm not sure of the purpose of setting the question mark as another button as well). Oh and being able to use the ESC button to close menus would be great too.
I feel like the character moves a bit too slow especially considering there can be large amounts of empty space. A speed increase, sprint option or even movement upgrades later on would be my suggestions.
Despite the flaws I can absolutely see the potential of this game and it would be a favourite in this community if these problems are addressed so I hope you eventually update it with some quality of life if you find the time. Regardless, I thank you for your hard work on making such a game
