It's an interesting game for sure. You've created a medium in which players are able to create their own boss battles, and other players can fight those bosses. I've always been supportive of more creative games, anything with content you can easily create and share with everyone else. As such I rather enjoy playing this.
However, I do feel as if the creation of the Raybots is somewhat limited. You have a decent variety of weapons, but the movement is limited, and some essential elements of a good boss battle are missing, such as weakpoints.
