Why do these games only ever go to 99 levels? Is there something I don't get and it's only supposed to go to 99? You could sell packs to extend it or something because you can literally finish the 99 in a day or two. Challenge mode isn't that great and it's even more annoying that you MUST review to access it, instead of it being unlockable by playing the game. There's another game like this that has daily new puzzles, you can unlock the challenge mode, and tons more unlockable skins. It was only 99, too, though. Make more levels for these games. Otherwise, they get boring quickly.
