I appreciate the feedback!
The air deceleration is definitely a problem, I think me playing the game over and over blind-sighted me while my friends didn't pick up on it while play-testing. I am redoing the movement script for a post-jam update and I will happily make sure it feels far better and more predictable.
For the controls, It did cross my mind at some point that the controls being locked would bring major issues on accessibility, it should have been a priority especially for a precise and difficult platformer. When the judging is over I will definitely feature the option in the update.
