It's quite profitable

Among the point-earning games in Recipe Challenge, this one is quite profitable. If you keep tapping the center edge of the screen with both hands, I think you can finish it in about an hour and a half. However, the more you progress, the fewer points you earn per session. Also, since the condition is to launch 100 blocks, you don't need to worry about puzzles. But, there's a forced ad when you continue, so I think some adjustment is needed there.
