Hey, this game reminded me my own game idea in a way ahah. But you made it really effective and engaging with simple and intuitive mechanics. I can play that all day!
The only thing that I didn't like was that once you reach the edge of the ground, your character immediately falls without being able to jump. Maybe you can use a timer that allows player to jump in the last moment? But overall, the starting menu was intriguing, each new level was engaging, and the game is satisfying to play
