Glad you liked it. If you unlock all 3 you discover a secret
I played 3 times and I did not find any secret, and that is because I am terrible at platformer games. I will try again. I also really like the cubes that are randomly moving and this makes it even more interesting during my jumps and trying to see if I can reach there, and that's how I was able to reach the red cube, and that felt good.
