If there has even been a game that needs staged progression, this is it. Think about the Rubik's cube, most people never solve it. Almost all who try never get close, it's that really hard game and I'm sure with enough perseverance you will get there... maybe.
Although Brick Block is immediately assumed to be the same thing, it really isn't from a difficulty point of view. Two colors with all 6 sides having the same color is dramatically easier than the Rubik's cube. I don't want to take anything away from what they made, it's clearly garnered a devoted following, and those who can appear to be magicians. I believe most of its success and prevalence came from the marvel of its construction, I still remember trying to pull one apart as a kid to see how it was possible, and again being confused by strings and wires. The more I look at it, the Rubik's cube is one game that you learn the moves and apply them over and over, other than variation, it is that one game. It's really hard but it doesn't change. At that point, it would feel empty, and without new challenges, ultimately it is one dimensional.
Very few people actually climb Mount Everest, I imagine that's what the Rubik's cube is like. Many more people enjoy a good hike and taking in the experience, that's more what I'm interested in.
This game is less about the construction and more about the experience of playing, learning and achieving what your mind could not before.
The first 6 levels are one move from solution, and they will have an intention overlay to show the player how to drag. These will communicate how to play and the loop of success.
A real surprise was tackling 3 colors once I had mastered 2 colors, it's not at all the same. In a way I had to unlearn what I learnt previously to solve 2 colours. I think it's because I had attempted to solve one of the side colours as I would have for a 2 color brick block. As such it felt appropriate to go back to the "start" without the guidance levels.
