Really interesting concept, I had fun weaving the chroma lance through the maze! It feels great to get a big bunch of enemies all in one go!
Sometimes it was a bit hard to play though. First of all, if I hit a wall and get stuck off course, I can't get away from any enemies (Which is really frustrating).
And secondly, there are way too many enemies at once. When you get to a certain point in the game, leaving one portal open is guaranteed death. While it should definitely ramp up, it feels like too much.
EDIT : Also it looks like there's a bug when you shoot something that's too close. It seems like the chroma lance disappears when it enters a collision with the player, but if the target is too close then it never stops colliding with the player, so it never returns properly.
Still a really cool game, that had a really nice feel to it. Awesome job!
