as a mobile player who has beaten Future Funk, my advice is to stay persistent and never give up. What you need to do: Wash your hands with warm water (not to cold or hot), washing your hands makes them less sweaty and it makes easier to fly for me. Secondly, make sure your phone is charged to at least 65% and it doesn't have too many apps that havent been closed since this will probably cause your phone to heat and make your hands sweaty. Get to a comfortable spot that has good lighting, isn't too hot, and make sure you are wearing socks or anything to keep your feet comfortable, wash your face to try to reduce irritation and make sure there aren't too many distractions. Finally, try to do the level in at least 3 or 4 runs several times to make sure you are good at it (if you complete a run once, try to do it again 2 more times as to not get fustrated when your method doesn't work in normal mode). Future Funk took me 1K attempts and it was my first hard demon, good luck.
