Cool game that started strong, but that second area where the entity chases you seemed weird. I got to the point where it seemed I had to crawl into a green pipe, I would seemingly fall through the ground (hard to tell due to how dark it was), and the game would just send me back to the start of the level.
However, I really enjoyed the game up until that point; I just wished I could have figured out how to finish it. Great project overall!
