Fluids are also REALLY WACKY in 2D. There is no "down" for them to flow so they follow flow vs antiflow rules -- an open floodgate generates a "flow", a closed one generates an "antiflow", etc. This doesn't work very well and has on occasion produced perma-flooding, perma-anti-flooding, and both -- resulting in the phrase "there are roving clumps of sentient lava outside".
Also, farming is extremely hard, there's no dirt so you have to make your own mud (which disappears every year), workflows tangle until your streets are overrun with garbage, dwarves don't realize when items they want to wear are on fire, and you can't forbid anything.

Opened it up to look around.
I don't know how to find dwarves! (Q) doesn't do nearly as many things as it's supposed to! Material selection is all out of whack!
Oh God, where the hell is my stocks screen?!!??!
We don't have any bones! We don't have any doors, and I can't find the mason's shop! We don't have an anvil! I think?! I can't find out!!! We don't have any booze either, maybe! For the love of Armok where are the farms?
We have a giant pile of very expensive gems and iron bars just laying around outside, but everybody's busy hauling [Idon'tknow!?!] how many corpses and a giant pile of clothing from near the magma river that I don't care to dwell on. And even if I could get them to move stuff, I can't quantum-stock all these god damned rocks to put down a stockpile and I'm afraid of causing a cave in but why isn't the magma river collapsing then and oh god oh god I can't forbid things
I'm through the looking-glass and flying blind here. I'd have an easier time of this if I'd never played DF before than I am now, trying to unlearn all the 3D stuff to play retrograde style. This is going to be hard.
