Just beat the game. Fun stuff, I like how you end the game as basically ruling the known universe and hanging out with Jane Austen.
I've repeated that "stuck in the air" bug. At least for me it, it would constantly happen when:
You get the nuke upgrade for the super jump thing and then on your way down hit an air vehicle causing the nuke to go off.
Sometimes you'd hit the ground but you couldn't move or do anything. The game didn't crash because enemies were still moving around and you can access a few menus.
