I really liked how everything including the start menu and UI were upside down lol, very unique take on the theme, nice work!! The upside down bird sprite in the screenshots looks good, but in my playthrough I was only controlling a white circle. I made it through 4 pipes and then no more showed up, but I enjoyed that first little bit. If the bird moved a bit faster horizontally that would help too imo. Nice job on re-making flappy bird, but upside down, keep up the good work!
