This game is pretty much another New Super Mario Bros Game and delivers on that expectation. Because there are so many similiar entries in the series, it has a hard time standing out among them, but the coin gimmick at the very least incentivizes you to approach playing it differently.
Getting a lot of coins also means you're never really going to run out of lives which I enjoyed.
Most people don't seem to look back on this game fondly, but it introduces some nice new level elements that make this game worth playing if you're looking for the video game equivalent to comfort food.
