I get it, you need to make money. But he ratio of ad time to game play is probably 60/40 ads to game play. Plus there is no real game progress. Watch and ad, push the guy off, watch an add. Play again watch ad, push, watch ad. Same guy same tower same thing. Over and over and over.
It could be a fun game. Significantly drop the duration of the ads, make the tower type a choice, maybe make it so you can add stuff to the tower to fall through, plates of glass. Get creative.
Anyway I played the game for 10 minutes, couldn’t take the number of ads, deleted the game.
