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.

Spent some time to figure this game out. Took me a while to understand that a composter is needed for new plants.

Once i bought the first one, things accelerated until i maxed out my power. I thought i could get more money selling nut butter, but that didnt seem to be the case. The grinder wouldnt automatically transport butter through the pipes to the store (or i did something wrong). Manually placing butter there didnt seem to profit me that much, it just seemed it took longer to sell?.

Games graphics are neat, needs a main menu however so i can quit without pressing the window x. UI isnt that intuitive. For an incremental game you should be able to unlock things step by step. All the buildings in the shop overwhelmed me at first and it didn't seem logical that the most important building to start would cost 100 coins right of the bat.

I can see myself spend some hours building a nice nut farm with this if it gets more polish, sounds and music.
