I tried to tutorialize the color usage by putting some text on the ground like "Use [2] for jump", "Use [3] for speed", but with the other things you said, there was definitely things I couldve done to make the game better especially game design-wise since the puzzles were extremely basic. It was basically a minute long tutorial haha. It was my first game jam so hopefully I can use this experience to do better things for the next one I join. Thanks for the feedback! :)
