Your art skills are awesome! Wow! The way you implemented the glow, the small rays that you added and the overall pixel art really take the atmosphere to the next level. And the music really fits the theme of the game and you feel like you have to grow your way out of danger. You can really feel the dread.
The gameplay is also very nice and unique, and the camera being zoomed in just enough so that every time you make a move you never know if you're getting closer or further away from your goal really adds to the tension. Great job!
