Engine units can be crafted by hand. Maybe unintentional, since in the basegame they require an assembler, even though they don't contain fluids.

I hate this mod so far. ;-) Keep up the good work!

Thanks! Send photos of your base when you're done online!

Yeah, the engine handcrafting is unintentional. That being said, I feel like I motivate the player to automate stuff enough already, so that may be left in as a little treat for the players.

Don't know about the motivation to automate stuff in the early game. I've finished a very low volume green science spaghetti base (https://imgur.com/a/W3gcs3m) and while building it, I was so tempted to just handcraft all the science needed for rails.
Given, there are a lot of ways to play this game. Lets see how I can fit a rail base in my achipelago map, where building space comes at a premium.

Playing this makes me feel like learning the game anew.

Excellent work, XD

I may buff belts and underground length, and make bobs inserters a dependency in the future.
