I agree with the feedback below so I will not repeat what has already been said.
First of all congratulations on publishing your first game! Even if the game has some issues it is still a worthy achievement to be celebrated!
I fell out of the world - there should be something in place to keep this from happening or handle a reset when this happens. I also thought the game crashed on the last level.. But I think maybe I just died as shooting the area with the stick gave me a win game screen.
Definitely keep up the work, this is a fantastic start!
