Hi! I just played this game for the first time and I had a huge issue in the final part (the tornado part) of the boss fight. I played the boss stage FOUR TIMES and I couldn't finish it because a piece of debris got stuck near the door frame. Finally, after some research, I found this was a very common bug and I could solve it based on people's experience: I lowered the resolution and the graphics (by a lot). Not only it helped me to finally conclude the freaking fight, but it unlocked a WHOLE lot of things for me: the battle was WAY faster (agile), the music was different and I got item sounds I didn't get before. The camera angle algo changes mid way destroying everything, and that didn't happen before for me. Hope this is useful for someone that's also struggling with this! This bug was one try away from ruining the game for me.
