Funky and stunningly drawn arcade game Muramasa Rebirth from Marvelous (localised by Aksys) leads the way on the Vita's EU PS+ collection in May, ably abetted by the consigned-to-the-bargain bin Everybody's Golf, although there's plenty of neat DLC for it.
What that does make me wonder is what is developer Clap Hanz doing now? It dabbled with Tennis on the PSP and those fun Stress Buster mini games, then uprated Golf for the PS3. But what are they working on next? Their last product appears to have been a smartphone Smart Golf game, but surely they have something bigger in the pipe?
