Hello @Olof Darin! Welcome to the forum!
I am listening with headphones as instructed. I actually think this is quite lovely with some unease and discomfort inherent in the slightly dissonant language you employ. But I think this proceeds quite logically and melodiously throughout! You might get even more attention from fellow pianists on this forum who have also played their own sonatas like you have such as @PCC and @Henry Ng Tsz Kiu, if you posted a score. Your playing is very good, especially in the fast parts! I don't think I've heard any obvious mistakes. I think I like the soft, chorale-like parts of this movement the best. The bell-like effect you achieve through your use of octaves in the extremes of the piano register is also quite creative! Thanks for sharing and good job!
