I tried it out for several hours, so here are my thoughts.
Input/output arrows in pipe ui shouldn't disappear, when you click on one if that direction is already taken then it should just auto-flip the pipe. Pipe placement could be easier, maybe click and drag towards where you want your output to be. Pipes themselves are kinda confusing, can take input from multiple other pipes but only one machine.
Some produce can be made from different materials and I'm guessing that why sometimes machines don't accept it as input, that needs a fix. In some cases you can't insert materials by hand, I think it's only when machines have 2 input areas. Have no idea how to balance recipes that require 3 items, with only 2 inputs it feels I'll always run into a problem.
Can't suggest anything for balancing, might be my skill issue, but I keep not having enough power and all the good upgrades are too far away/expensive and require unraveling all the spaghetti that I've made.
