I've played this game on and off. I've always had fun with it. The constant ads always draws me away from app games. App games used to remove ads whenever you would buy anything from the store but with this game it doesn't seem to be the case. Besides all the ads it's a fun game and it would be even better if it wasn't interrupted after every run as there is plenty of ads for coin bonuses, character upgrades, revives, and building upgrades which is fine and I usually always go for those anyways.
