On the PlayStation Blog's weekly The Drop article, the game is listed as "Completely free for life to download and play!" The dedicated site for the game on PlayStation's website reiterates that same claim. Consider all of the game's pre-release literature.

Of course, such an approach is solely the prerogative of the game's developer, but even for a free-to-play game that could be easily downloaded, sampled and deleted, Montezuma Blitz borders on the intentionally deceptive. And you'll need them when you use all of your lives up after five or ten minutes, because Treasures of Montezuma Blitz is awfully stingy.

Treasures of Montezuma Blitz is a microtransaction-laden free-to-play game that neither hinted at it requiring microtransactions nor speaks of them in-game.
