Too difficult, too soon. Ease up a bit. We don't mind ads but making a game too hard and mathematically impossible to win without paying is a damn shame. Nice game... Beautiful artwork but sullied with the inability to actually win, makes my review a 1 star instead of 5. These reviews mean nothing to developers until the masses start reading the critical reviews instead of the Google play fake positive reviews and stop playing. Until then, fools and their money will keep parting ways.
