Wow, I didn't even think to count. You can see it in the ending credits—I added all the different types of clothing there.
Regarding leniency, each level always has several possible correct answers, even without regard to character color. Perhaps only LOTR one allows only two correct answers; the others have many more. This is a very interesting topic, by the way. If you add more possible solutions, the chances of solving the puzzle by chance or brute force are higher. If there's only one solution, there's a chance the logic will be unclear. I tried to find that balance between the two extremes.
Thank you very much for your review, I'm very glad you liked the game!
