Congrats on publishing your first game! It reminds me of Pokemon Stadium on N64 where there were mini games involving spamming the button, haha. Keep up the good work.

The game say and use Right, but your description say left key.

And I think it needs more something, the player only move to the right. Maybe you can add some stamina that need to be recharge by staying or not click/hold the right button. And if the stamina is full, you can dash or running faster.
