There is a timer

Good game but time is stressful
JJLigaya

Great game, but I spent more time watching ads than playing.

I get that you want us to purchase the full game without ads, but geez. Every wrong move is a 30 second ad. When you throw a hard level out there, I’m watching long ads on repeat. I just don’t have the patience. Total frustration. Please fix it because I love the actual game.
