Not bad! It definitely feels a bit empty with how much open space there is, and the jumping is a bit floaty, but the overall gameplay worked well enough. You might also consider working on your audio -- it was very quiet within the game.
Regardless, not too bad for a 3D game made in a week. I was especially a fan of the text you chose to dedicate to the theme, but I'm not too sure if it connected well to the game itself.
Keep up the good work!
