One bug I noticed while playing via proton experimental: If you're at a certain weight, cargo elevators that have walls on them will teleport you straight to the top. and you won't fall back down. I noticed starting at the third to last weight range on the orange lizard.
It's also incredibly easy to accidentally cheese the caves - if you build a structure on the first ledge to the left, the tiny reddish-pink slimes will get stuck in that corner and continue spawning in large enough numbers to completely fill the enemy cap, allowing you to go through the rest of the caverns in peace.
In terms of balance - those tiny slimes don't have much health, but they spawn in such large numbers that it can be borderline impossible to make any progress in getting past them, since actually killing them requires getting to the large slime spawning them and said large slime can often be out of reach.
