I think you used the two button limitation very well and a pretty good concept. But the first time I played I had no idea what was going on I just saw that you could jump and dive by pressing a+d and so I thought you were supposed to get the balls to the line fastest so I did and then waited for a minute and I died and I couldnt restart so maybe add a tutorial next time and maybe say what the goal of the game is in the Description. After I knew what I was doing it was a decent game.
