Wow, this was a very fun game with some cool and interesting mechanics, and it felt very good to play! I have just a couple minor suggestions that I think would have pushed it to the next level of great for me:
1. Maybe make the battery charging mechanic more clear. I spent about 10 minutes spamming those buttons before I realized that you can hold them down, and it wasn't very clear from a gameplay perspective that holding them would do anything different when there was no indication of such.
2. Once the screen gets split up in the light "run", I would suggest adding a way to toggle off the left side of the screen, as the right side starts to require large amounts of scrolling, since I'm trying to both keep the battery levels high and check my color energy amount.
3. This one is quite minor, but the colour-changing text could use some sort of white outline to make it more clear to read.
Other than that, the game is awesome, keep up the great work!
