Love it! I like this kind of games and it was well-made.
I see a lot of suggestions in comments but everything was fine for me, even the text that looked small and hard to read at first.
Well... There is one function that lacked a bit and I could only achieve at the cost of a part of production: something that throw away a ressource like the abyssal door does, but only when it's full. Putting a splitter and an abyssal door do that but 50% of the production is lost as the splitter alternate. I added another splitter and a merger to make it 25% loss.
Also I think to be able to move the machine without breaking all the connections would be nice, so you can move without destroying all that you connected.
