Spotted this on HUKD: Bleed+Bleed 2 for £3.69 or £1.29 with Plus. They're short indie run and gun games with slo-mo, air dodges, reflecting and local two-player. Only done the first one and it's good fun. It's pretty much a one hour boss rush, clearly inspired by Treasure, with one section being a direct rip from Gradius V.
Wow, and all four of the PSVR games on my wishlist have got healthy discounts too. Statik, Headmaster, Ultrawings and (oh please be good) Pixel Ripped 1989.
Ah ok. I have used the PSN wishlist on the app and web. One appeared in the Xbone interface lately - I have yet to find it elsewhere though. Very random.
