I developed games for fun, one of them it's in Google Play with 9500 downloads.
I enjoy developing games, so I wont have any problem making your game.
I have a lot of experience with java game programming too, I have some game projects made from scratch in pure java, if you wants screenshots or something, just tell me.
It would be great to know more about your game, because the price it's estimated, and maybe I can make it in fewer days.
¡Good day!
