Too slow to get $2, it took me 1 minute pressing to get $2 to get $25 i need to press like crazy for 25 minutes that's too long. Make it like 5 second $2 or something to get people interested in the beginning. Right now I quit before it reach $25 as it take too long to get there.
But the idea is solid and great game if you can make it easier. 3 star.
