Why my App Inventor Game not working Properly?

Hello, Inventors,
I'm making one fighting game with MIT App Inventor, after completing this game this app is not responding or running very slow so I'm not able to play this game.
So may I know the error or problem, I have done something wrong with coding or something else could you help me to resolve this.
I have attached the aia fileFightTing.aia (1.6 MB)
Thank You


@TheCodingBus I've loaded it, and every time i open it up in the companion app, my whole tablet crashes. Don't know what's up with that. Still looking at the code.
And nice UN, btw.

Edit: I don't see anything wrong with it. It's super basic, and seems like it should be alright. Check how fast your clock is firing.


I think the size of the images could be a problem.


@Peter I think i agree with you. After loading up different pictures that are smaller, it seemed to work fine.
