It's a fun puzzle jewel match game, as they usually are, but as in any "free to play" game like this, you are only going to get any real progress if you spend a bunch of real money on in-game items. So when you've spent between $30 and $60 dollars, you've basically paid for a full priced new game. That's fine, just don't mark the game as free to play when it can only be properly enjoyed if you buy things. It's the exact same formula that 99.99% of "free to play" cell phone games use which makes cell phone gaming horrible. Long story short, this really isn't free to play, it's "free to play" with quotes. Another game I can think of that's the same way is Warframe: grind the same levels for dozens upon dozens of hours, or spend a minimum of $20 and well over that for what you want/need. But if you like Marvel and jewel match games which are addictive, and are willing to pay to enjoy the game properly, this would be fun I would safely assume. Free to play is, for some games, including this one, a crappy cash-grab money sink that unfortunately may never go away.
There are thankfully a few exceptions. Research closely before playing any f2p game. Some games that are truly enjoyable f2p without having to spend money unless you want to include Firefall, Tera, Vindictus, Age of Conan, The Secret World, TF2, and DOTA 2. These are ones I've played, more are out there if you look.
