Hi! Looks like an interesting project. I tried to run it but can't. I have Java 1.8 - that's actually what installs when one follows the link in your instructions. Not sure if a 1.7 game can run on 1.8.
I wonder why there are no comments about your game. Could be that no one knows how to install Java (or has a similar issue as I have). Or it's the font of your store listing: it was hard for me to read. Maybe porting the game to Unity will be beneficial.
