Cool for a first game, man. I don't have much new feedback to offer besides what's already been said: nice twist with it actually being a 3D game though I wish you'd done more with it, the jumping was inconsistent and a little frustrating, but the narrative you were telling was quite intriguing! Keep it up and you'll only get better from here!
I am curious about something though: Why did you only use 2 of the 48 hours allotted?
