Very basic, but a good start. Looks like you have the "stat" and progressive side of things down. Now you need to give people a bit more of a goal to reach. A bunch of achievements for reaching certain goals. Perhaps some upgrades for certain goals. A reason more than just "reach 10,000,000" if you know what I mean :)
It is hard to play this for more than 10 or so minutes otherwise.
I really look forward to what you create in the future!
