online multiplayer watergun hentai game?

some may have noticed I have been working on some Umichan 3D multiplayer online (um3do) stuff recently. and is really in preparation for something else actually. Instead of how UM3DO is currently where you attack other students with sentinels, I wanted to make it a water gun/park theme multiplayer shooter.

wanted to use this environment. with a few effects.

the idea of water gun stuff in inspired form Senran Kagura: Peach Beach Splash
