As much as I've grown to detest this term, Skyblazer is an "underrated gem" of a game. The combat feels fun, you unlock all sorts of cool special moves to take down enemies and traverse stages, and the boss fights are (mostly) cool. There are some that'll make you pull your hair out a bit, but the game isn't punishing at all, and you can continue after running out of lives as often as you need. Absolutely consider checking this one out!
