This is a good puzzle game with an interesting concept. I liked the idea of manipulating cubes in 3D space and trying to figure out the connection between the puzzle name, hint, and cube placement. The color matching and cube locking system gives the game a unique challenge.
My main feedback is that I wish I had a clearer understanding of the goal for each puzzle. I understood the controls and how to move, rotate, and lock the cubes, but I was not always sure what I was supposed to solve or what the required condition was. A little more guidance, maybe through a clearer tutorial, example puzzle, or stronger visual hints, would help players understand the objective before they start experimenting.
The game definitely fits the theme of “Connections,” especially with the way players have to connect colors, cube faces, puzzle names, and hints together. Overall, this is a strong puzzle idea, and I think it could become even better with clearer goal communication for the player.
