Originally made by Bob Nystrom [1] who now works on Dart, it is now maintained by ruby0x1 who is a game developer and most importantly creator of a game engine that uses Wren as a scripting language [2]. Unfortunately Luxe is still not publicly available (closed beta), which I admit is a bit of a frustration for me as I've been following development for a few years, but it does show a lot of promise and in the meantime I've become a happy user of Godot. I keep Wren in the back of my mind as an easy-to-embed scripting language in cases where you could integrate Lua (which Wren outspeeds) but not LuaJIT.
