It was great and amazing for a while before a lot of things were locked behind paywalls... I wasnt as motivated to play because they locked some of the lesson plan away. Many things suddenly were locked that weren't before and shouldn't be after playing for only 2 days... They locked away all the games except for 3. There aren't any ads, but there are many paywalls. I would gladly take a few ads to gain access to my favorite games and features again.
