I would have liked to see the white squares have some kind of advantage to complement the fact blue can double jump. Something like the white squares being smaller and thus able to fit through a narrow gap. As it stands blue can overcome an extra obstacle type over white which coupled with the fact that it's harder to control 2 things over 1 makes it so the player almost always wants to be merged if possible. Otherwise I liked the puzzle presented in the game and the mechanic itself. I also like the relaxing music used.
