A potentially finished version of my game

After a lot of work, I think I am finally finished.  The biggest issues that got fixed were:

• the user interface (as shown on the right)
• the game crashing
• the lack of a pause function
• high sensitivity

I had to decrease the size of the images so that it would stop crashing.  I think I have found just the right size, but if it still crashes or the image quality is too low, let me know in the comments.  I may add some kind of noise, but I don't think I'll put too much more effort into this because I am ready to move onto my next project, whatever that may be.  Here is the APK and Source Code.  Please check it out and tell me what you think.  Thanks.
