Jumping on barrels often sends me and the friends I play with flying across the room. It's fun, but a bit chaotic. It's not nearly as bad as it was when I first played. But they still fly around/send us flying every now and then.
Also just for screenshot potential. I'd love if we didn't slide/bounce off of each other's heards, I want stacks! (Other than that, the only cosmetic feature I want more than anything is some emotes for the launch bay, I wanna sit down with by brothers!
That was converted from a bug to a feature long ago when we got the barrel physics to a state that was deemed not completely insane.
Dwarf stacking would be fun, no doubt.
I think we actually have a sit down animation but it has not been implemented because of priorities.
