Somnilithe
WARNING: this is a yearly updated multiplayer yume-nikki fangame featuring characters from .flow. Please follow for updates on characters, story, and mechanics! The story and some characters are completely original.
The world has ended. Reality is collapsing into the dream realm. Survivors, skilled in dream-travel, now battle for scarce resources. In this desperate moment, lives are taken, souls are reaped, and friendships manifest in the strangest of moments.
The dread Uboa awaits you, will you brave the deepest nightmares, and liberate the dreamworld?
Somnilithe is a singleplayer and multiplayer game where you choose a dream character to travel through dream worlds while collecting resources, weapons, and abilities. It's most enjoyed by inviting your friends to play alongside you, but can also be played alone.
IT IS RECOMMENDED TO PLAY THE DOWNLOADABLE VERSION FOR STABILITY AND FOR MORE BEAUTIFUL GRAPHICAL EXPERIENCE.

It's quite early on into it's development.
But got a really quite strong atmosphere, something that you can easily get lost in. A good mix of the desolate environments and music. Platforming's fun, I want more challenges involving it.
The gun's also pretty great.
I see alot of potential for it in the future. Goodluck.
(Also I'd focus on the single player experience)
I've tried your game and there's no one online lol, but I think it would be entertaining if I played it with a friend who is a fan of YN, even for role-playing. I also liked the school setting. It is certainly an interesting project and it would be great if there were more weapons or items related to YN, but overall a good game to play with a friend.
