When Meatloaf said he would do anything for love except that, do you think he was referring to angry mobs with pitchforks and complex platforming puzzles suspended over deadly spike traps? Because I think that's reasonable. But apparently I'm not as much of a romantic as the two titular heroes of Meowbeast's Jim Loves Mary, because even though Mary's parents disapprove of our boy Jim to rather extreme degrees, they're willing to do whatever it takes and brave any danger to be together. Use [WASD] to control Jim, and the [arrow] keys to control Mary, aiming to bring them together in each level. Mary can fit through smaller places and pass by her family unharmed, but since they'll take a swing at Jim whenever possible, you'll want to try to grab all three hearts on each stage, each of which will allow him to survive a hit... if not a plunge into a pit of spikes.
Mechanically speaking, Jim Loves Mary is essentially a cross between the Fireboy and Watergirl series and games like One and One Story. Just because it's familiar, however, doesn't mean you should pass it by. A lot of games will task you with gathering X optional item on a stage, but by making the hearts valuable to you through allowing Jim to survive a hit, you've got incentive beyond simple hoarding to snatch them up. For some players, both the challenge and variety may ramp up too slowly, and the game is never going to become a real brain-twister. But it's fun, charmingly designed, and engagingly casual in a way that makes it a perfect choice to fill up spare time with just enough puzzling to give your head a workout without breaking a sweat.
