PSA: If an unhealthy obsession with playing dozens of different computer solitaire games is a symptom of your particular mental illness, I recommend you seek professional help before buying another title.
There are some interesting novelties here like on-card timed bonuses, and the strange choice not to use a complete deck (instead, there are multiple copies of the same clusters of cards); it's not clear what this latter gimmick achieves (perhaps making it easier to thoughtlessly generate a lot of layouts that otherwise wouldn't work).
The art, music, and design can be quite pretty, but the perfunctory story, jigsaws, and hidden object puzzles are badly done and don't add anything despite being a good idea, in theory. The rest of the mechanics are standard to the genre.
The worst deal breaker here is a needlessly sluggish interface: special cards and unlocks trigger interminable (perhaps I exaggerate) animations during which the game is unresponsive to input. If you are used to playing snappier games, it breaks the flow. I prefer to waste my life at higher speed.
One more point, in case you didn't know: The solitaire variant all these +1/-1 games are based on, Golf, has you play nine "holes" or hands. The best of this genre (Regency, Faerie Solitaire, etc) retain this match structure, and give you goals you must attain during a "course" of hands. This is where most of the strategic thinking comes in: which hands should you reach for a particular goal on? How should you manage your wild cards and buffs? Usually on easy mode you can take a mulligan to replay a hand, but once you've moved to the next, your results are locked in. Distributing the RNG over the course gives you some meaningful control without diminishing the challenge or completely eliminating randomness.
Unfortunately, a lot of games (like this one) remove this structure, effectively making matches consist of only a single hand, eliminating inter-hand strategies with less of a price for failure and thus less satisfaction from victories. When you can just redeal a single hand over and over until you get lucky, eventual progress is assured but empty and there is no real need to improve or make strategic decisions. This crosses the Rubicon from "casual" to "mindless." It's like putting all your money on a single roulette spin, as opposed to entering a Texas Hold 'Em tournament. The former is mindless gambling while the latter is a skillful game of risk management.
In summary it's a pleasant enough game for a couple of bucks but only worthwhile if you're bored with twenty of the other better solitaire games.
P.S. There's also an annoying late-game bug where using the swap power after a card is burned leaves the swapped card invisible, and thus you must GUESS which card was swapped by clicking around until you find a legal move. Not game-breaking but it gives you a sense of the (lack of) quality here.
