I played with your project 20 minutes. I cannot define it like a game - but instead like a artistic experience. Overall I like it. But technically this is really weird. I asked myself how you did that. The dimensional door is really smooth and some shaders are impressive. I cannot figure out how you did that. For me, it is a little bit disturbing. Thank you for this experience in a great aesthetic. I would like to see more - maybe a full game with a real gameplay. Great ++
They only way to define this "as is" as a game is to define art as a game, where the win condition is a completed piece, and the fail state is any happy mistake that happens thanks to how the paint guns work. I doubt many people would reach that far just to define it as a game though, I might if there was any other interaction besides just painting.
