Ikaruga is one of the purest gaming experiences out there. It's a brutally difficult shoot-'em-up, the kind of short-but-sweet game that takes a clever mechanic, explores it to its full extent, and doesn't pack on any unwanted fat. You could easily spend a hundred hours learning how to scrape your way through all five stages without continues. Then you could spend a thousand more perfecting your score.
After making its way to Xbox 360 in 2008 and slightly more recently PC in 2014, Ikaruga has found a new home on the Nintendo Switch eShop. The port has everything I've come to expect: remappable controls, two-player local co-op, downloadable replays, an art gallery, and a whole lot of misery.
This version of Ikaruga also includes a vertical screen mode, meaning you can turn your Switch on its side, prop it up, and play this essential shmup as it's meant to be played.
