I wasn't exactly sure what my objective is here. Was it just to survive, or survive and try to achieve 100% light? I also didn't find the teleportation to be very useful, in my playthrough, since enemies were coming in from different directions.
The music was pretty cool, but it didn't really fit with the gameplay and enemies. Like, I should feel like my life is in danger, when I'm either being closed in by enemies or when I'm running out of light. Though the enemies did look interesting.
