It’s good to know that certain games still cater to the old school crowd. Super Meat Boy did it. Donkey Kong Country Returns did it. And most recently, Hard Corps: Up Rising did it. You can now add Moon Diver to that list of highly challenging games. Developed by feelplus and directed by Koichi Yotsui, this spiritual Strider quasi-successor delivers a massive dose of retro challenge but mixes in enough modern elements to make it a worthwhile game. Though it has a few glaring flaws, it’s hard not to be captivated by the experience.
