For how utterly indepth all the mechanics are, I found it surprisingly accessible. After some initial futzing around to get the different combination recipes and control modes.
I swear you're going to have to do like 120 iterations of that tutorial until people stop complaining about it, though. Just one of the timesinks that come with making a game this insanely deep. I liked the general pacing and controls, it's a fun, proudly niche game.
