I am hesitant about both the App and the actual game for the comp. I was super hyped about this game. I followed stories on its creation over the years, and how they made this game was no small task. It is a very deep, involved process to create the actual ability to evolve.
But, tne concerns about actual gameplay, and lack of containing prolonged interest is always a red flag. I will wait to see what comes out of the next few weeks.
I bought the PC game and played for about 5 hours straight and got to the last stage (space.) As soon as I got to the space stage I turned the game off. I haven't played it since and it's been nearly a week. It's a fun game, but I feel like I will only pick it up again if I get extremely bored. Wait for a price drop if you are interested in buying it because it is not worth $50
