I like the Pixel art,  it's cute. I don't think I can give very accurate feedback since I'm using wine to play on Linux. I will say that if it isn't a "me-specific problem", you might want to make jumping and moving better. Also, I don't know if pic related is intentional with the invisible platforms or once again if it is a "me problem" kek. I hope you get some proper feedback from Windows users, but I'd still like to play your game in the future!
