Mewtwo shrine
Oh yeah, I made a thing for Mewtwo Day this year, a 3D Mewtwo shrine that's viewable in a web browser (on desktop. It needs keyboard and mouse to move around.)
Temple wall
Waterfall
Multiplayer. Behold, cat.
Hidden cat shrine
I've also been making some extra, unrelated areas to put in it since I already got the framework for loading scenes and such made. Haven't released any of those yet.
