For your age this is a great submission! Congratulations on that!
The camera can be a bit wonky, sometimes obscuring incoming enemies, but it is workable. After the first upgrade I chose the decreased dash delay, which made it pretty much instantly spammable, hahaha. Overall a fun little game; I hope you learned a lot from it.
Edit: Oh, btw, I recommend playing in full screen. Otherwise the help textboxes are obscuring the view.
