The Flappy Bird DNA is clear but yobitjoy1 put it best — accuracy over speed is what makes it distinct, that's a different kind of challenge than most jam entries. Alix Krag's "took a second to get it but then I had fun" is actually one of the better reactions because it means the gameplay hooks you once it clicks. The main actionable feedback from redkoala64 about the tap giving too much upward force and the fall being too quick is worth looking into post-jam — tuning that gravity curve would make the game feel noticeably more controlled. RicoTV's idea of making it vertical to better fit the theme is an interesting thought too, though the horizontal direction gives it its own identity. Aur WkPlayGames ka "can't stop playing" clearly bolata hai ki addictiveness toh hai game mein!
