You can play it now
Vanillaware said it was working on it, and last weekend, the studio released the Odin Sphere 8-bit browser game. You play as Gwendolyn, who has a standard attack, aerial dive attack, and a glide at her disposal.
I have to say, it’s actually not bad at all for a side project. The controls are pretty responsive and I dig the art style — especially that chiptune main theme! The Leifthrasir remake was released in Japan last month, and is coming in June in the west.
