I played for a bit and got as far as automating a few things (metal / wafer production, dismantling large chunks of dirt, mineshaft driller). Overall the base mechanics feel very solid, and I was surprised the thoroughness of some of the interactions (like when my unanchored combiner pushed itself up by ejecting its products). It feel like it has the depth to encourage
My main pain points were that the blocks in the guide menu were rendered too small to recognize, and that I was confused during the initial hints since I couldn't figure out the build/place controls until I looked at the options. Other than that, maybe it would help to define some high-level objectives for the player to help direct them into learning what they can do with the game, since I find that kind of thing helps me when I'm getting into Minecraft automation mods (I haven't played many automation games outside of that).
