The music is stolen from various games, not like it was very good to begin with.The emotes are pandering, and mostly come off as pretty stupid.In other words, it's Club Penguin but with math. Not to mention, it also rips off Club Penguin since you get to play minigames, you use your mouse to click to make the player walk, have a pet, having a membership, wearing outfits, making you log on every time you go on the website, meet online, be friends with others, design your house, buy decorations, do achievements.It makes your character look like a dummy who doesn't know what math is.In other words, it wants children to cave in to microtransactions. This is why many parents complained about this, as it can urge children to pay $6-$10 per month for a membership. It gives you a limit on the number of pets you give, doesn't let you evolve pets, you get only ONE chest while you're exploring each world, and you get stupid-looking clothes. You can't do most things without a membership.Loud and obnoxious voice acting with Slurpy being the worst as he yells or talks in a loud tone for everything he says.The story rips of basically every educational game and the Sonic franchise.He is also a weak cartoon villain who passes up nearly every chance to fight the player.
The Puppet Master tries to mind control everyone, so he stops everyone from learning.
