If I open the game, the daily reward calendar opens automatically and provides the daily bonus.
Fantastic five opens automatically after I finish playing a level. Which means that I am already at 0 lives left. Maximum reward will give two time-limited boosters. With zero lives it is obvious that it is absolutely unnecessary,
Please optimize the event rewards. If any element of the game gives time-limited boosters as a reward, give it right before I play a level. It can be the point when I enter the game similarly to daily calendar.
You did optimize this element once in the past but you changed back the delivery method in a few weeks afterwards. I really liked that way.
So all in all avoid giving time-limited boosters when I have zero lives.
