Dream vs. Dream is a free, community-developed #fighting game based off the characters and locations found in #YumeNikki and its various spinoffs and fangames. It's currently still in early stages of development, but development has come to a halt due to internal issues between members (among other reasons).
Dream vs Dream plays as most traditional 2D fighting games. Three playable characters are available in the current Alpha Release (v.0.2). Despite the early stage of release, Netplay has already been implemented. CPU opponents and story mode don't yet exist in the game, but local and online multiplayer as well as a training mode can be accessed.
