Keep in mind that I literally stopped playing at level 40 and had to Literally pause the game and hit give up so It didn't last forever. They were moving so fast they were slamming into each other and merging. At level 60 I was actively trying to lose. It's good mindless fun, but there is no risk of losing. The water level was MEANT to rise up, but it moves too slowly and goes down way too much after each line.
