When you enter the upgrade screen, if you press and hold S, then you'll back your character away, and if you then start hitting spacebar to hover, you will be outside of the map. If you then hit the elevator, it'll send it up and start the fight, but you won't up there fighting. Instead you'll be trappedi n the Upgrade room.

Not gamebreaking, as you have to actively do steps to recreate it, but you may still want to patch it.

Awesome game by the way, really enjoying dicing up the spider-trons legs.

Sweet! Yes, that one is fixed in the next release. Also the painful camera twist when you move after getting a clone.

Thanks for reporting

Oh, lovely. Well, wish ya the best of luck with the game.
