This merge 3/5 clone has Bonus energy available only for one certain hour a day. One ad watch a day for 30 energy. And pop up ads on the middle of gameplay. Somehow seems to be playing at 3/4 speed of other games. Kept it long enough to watch 3 ads then uninstalled. So u got 3 ads watched. Could have been more but there are more generous open source clones to try...
