This game seem pretty good. The backgrounds are nice and the sounds are okay.
You could improve the game by:
-Replace the "Enter 1 to continue" with an "OK" prompt.
-Make the attacks faster and more varied. The attacks take too long, and the action moves slowly.
If you fix those things, the game will be even better!
