Super Phantom Cat 1 & 2
Quite easily the longest game on this list, Super Phantom Cat has a ton of levels. No jokes, this one is absolutely massive. Gameplay-wise, it’s a distinctly Mario-inspired affair, but with its own style and gimmicks. Players get to unlock a selection of characters with their own special attributes. Levels are packed with secrets and special items. Various power ups are available, such as the ability to lay bombs or pass through walls. And finally, more levels and even entire worlds can be unlocked with repeated playthroughs and a keen eye towards secret areas. The sequel is more of the same, though I must admit I don’t find it nearly as endearing. Still, both are surely worth a try, especially since they’re free.
Cats seem to be quite popular in platformers. In Cattch, players once again take control of a scarf-wearing cat who has abilities that are more stereotypically feline. He can scale walls, jump around nimbly, and break things with his claws. This game takes a bottomless pit approach, and features levels with a great deal more verticality than any other game on this list. To make matters even more interesting, the playing area can be flipped on its side, essentially doubling the length of any given map. Once again, you should really add it to your library, though be warned that only the Android version is free; iOS users will need to shell out some cash for this one.
