ZPF is an interesting new Mega Drive shoot 'em up that, with its key-collecting secrets, hidden bosses, stage variety and fantasy theme, feels unique. It’s been put together with a lot of love, and while its clear the development team aren’t expert shoot-'em-up designers, they’ve still done incredibly well with the hardware. It’s frustrating at times, and many will be put off by not having continues or any method of practice, but those who persevere will find an enjoyable route to high scores and one credit clears. The issue primarily is the bare-bones Switch port that has zero additions or quality-of-life features, and suffers from a juddering issue that really damages the experience. If you’re buying on Mega Drive — and it’s recommended you do so — add a point to the scoreline.
