I never thought I'd see another Rubik's Cube in this jam! This is really cool, but I think the only problem I have with these puzzles is that I'm too dumb. I completed all the levels, but that was mostly through floundering around aimlessly. Just by the nature of it being a Rubik's Cube, there are so many decisions that the player can make at any time that it becomes incredibly difficult to plan anything out unless you're really familiar with these kinds of puzzles. I tried to make my game a level-based puzzler like this with the Rubik's Cube, but I couldn't figure out how to make it easier to understand besides making it a smaller cube, so I made it a more arcade-y game. When there's so much information to process (all the different tiles and how you can interact with them), and so many decisions you can make with that information (rotating the cube), it becomes near impossible to come up with a multi-step solution unless you're a mad genius, or you painstakingly go through each possible move. It felt like the complexity of thinking through the puzzle as intended grew exponentially with how many moves were required to solve the puzzle. It's so easy to feel overwhelmed and give up on thinking through the puzzle methodically. I still had a ton of fun playing around with the cube until I found a solution though, so clearly it's not that big of a problem. Feel free to disagree with this ramble, I've just been thinking about this a lot because my game has the exact same issue. There's a solid chance that I'm just terrible at these puzzles, and none of this is actually a problem haha. I hope you turn this into a full game, I'd love to play it!
