It's honestly the most complete game I have played in this game jam yet. Some levels needed some thought, but I managed to finish it. Nice difficulty progression !
I will just point out a very small detail that I am unsure if it was intended: In the 6:30 level, you can cheese the bottom of the level by grabbing one of the memory energies in the bottom right corner without getting out of the purple zone, thus not spending any extra energy and getting to the darkness with exactly the right amount to pass.
