Wow, I'm so glad that you actually suggested to add fixed levels to the game, because it was my initial idea (which I decided to postpone due to the time restrictions). It's a relief to know that it might be a good idea to add levels since I wanted to introduce puzzle elements anyways.
Hmm, I actually didn't think of too frequent pitch changes having such an impact, but I totally understand where you're coming from. I'll try to come up with something to make these transitions more pleasurable.
And yeah, some people already mentioned the delay with controls, I'll work on that a lot, because the game is already quite 'out of control,' making it even more with uncontrollable turning will be way too much XD
My huge appreciation for a detailed valuable opinion from you, it was interesting to read your thoughts :) Thank you
