It's always nice to see something that isn't Pokemon in this section, but this needs a bit of work...
- You should remove the watermark. You didn't make the sprites, and as poe said, this can be done in paint.
- The background for the loading screen and play screen are a bit distracting. Lower the saturation?
- The text on these backgrounds are really tacky. I suggest making a logo or something instead.
- There really isn't enough sprites to really do much of anything.
- ...Music? Is this necessary? Maybe mute it by default and then let the user unmute it if they want to hear it?
