It's got a unique look to it. I generally like the direction of the sound design. I think the ending is too different both in terms of looks and audio from the rest of the game. This can be made to work if it's a something you encounter multiple times throughout the game, but it comes off as abrasive after the buildup on the previous level.
I just think it's too short right now. I want to see a rich, sprawling universe in this style with all sorts of encounters, twists, turns and events.
