How good is this game in my opinion

Honestly this is a good game but I just wished it had less ads. Me liking the game of 24 makes this game perfect for me, the only thing dragging it from 5 stars to 4 is the problem with ads. Devs if this game, plz change this, and the game will become the Best out of the best
