It's a calming game with cute penguins. That's really the only thing good about the game. To progress, you are required you to watch many many ads. At least 100+. The ads aren't optional for progression, and you can't pay your way past them. 2nd gripe is that the quests (for eg, watching advertisements) just repeat with increasing amounts of griding. For example, research quest 200+ is just watch 6 as videos. And you must complete the quest to progress. I still play this. Coz... Penguins.
