Wow, what a great game! A Peggle idle RPG is a really fun concept, and something you can play all day by just having it run in the background while you work. Although, it was hard for me to resist the temptation to push the ball around with WASD, so maybe it's not completely idle :P
Btw, nice leaderboard implementation! It's a cool idea to include player stats with peoples' scores. I also added json database support to mine, but only used it to keep track of which level you've unlocked. This makes me want to explore that a bit more, maybe by adding stats like accuracy, number of each dino killed, number of reloads, etc, or a simple trophy/achievements system.
