Spending 90% of your time watching adds in order to level up is not fun. Unless you are willing to pay the devs an absolutely ridiculous amount of cash, you will not ever get past the primordial pond scum, or else it will take you years to evolve. Just another pay to win scam. That's unfortunate too because the concept is cool and so are the tactile actions, but that's about the limit of my kindness with regards to game play.
