Inti Creates, developer and publisher of the game, have released a playable demo of Yohane the Parhelion : Blaze in the DeepBlue for Switch and PC (Steam).
Based on Love Live!! Sunshine anime, the game is a 2D action game set in a mysterious underwater dungeon where the player controls Yohane and has to search for her missing friends.
The demo includes 3 areas that can be accessed earlier in the final product, but they have been slightly modified for the demo so savegames can’t be carried over to the full game.
