Yooka Laylee and the Impossible Lair. It's a 2.5D platformer in the style of Donkey Kong Country. The gimmick is that the Impossible Lair is accessible from the beginning of the game, but it's a long, arduous level. Finishing the other levels allows you to gather friendly bees (the Beetalion) which function as hit points for the Impossible Lair. It's a fantastic platformer and I needed almost all of the bees to complete the Lair. There's a challenge to finish the Impossible Lair without any bees, but the farthest I've made it is 20% of the way through.
