There are actually a few hidden cheat codes in the game. I think you may have inputted the unlock gravity cheat code button combination. I thought it was well hidden enough to not be run into. But it is Jump + Interaction + up + Ability at the same time to unlock invert gravity.
As for the both ability bug? Not sure what could have caused that. May have been related to activating the cheat code in a weird spot.
Regardless, you can also reset a room using the Pause menu if you get stuck.
