You could forgive the team at Platinum if they built their debut in the 2D shooter genre from the conventions of bullet hell.
The style made famous by Toaplan, Cave and their peers, after all, is often projected as the genre’s higher form, with its preference for excess commonly dazzling players, collectors and press alike. All of that might make bullet hell particularly appealing to a studio more typically focussed on energetic, happily excessive triple-A action games.
