I am genuinely blown away by all of the positive reviews of this game. The game only lets you play through the first two 'levels' for free; after that, the game is $5.49 for access to the remaining four levels. The biggest issue that I have with that is that the first two 'levels' took me less than ten minutes to complete. There's no indication of how long the remaining levels are, but if they're the same length as the first two, the price for the game is ridiculous.
