Nice concept, I love the mario galaxy vibe.
Maybe bring closer the camera to the player, is hard to see the enemy coming up front.
The flash light popup is misleading because it has a close button on the corner "x" so the first thing I tried was to click it, but there is no mouse visible .
The "ESC" key feels like a more natural way of closing popups at least on windows, Maybe add a small text to indicate the player how to close it: "press enter to continue" but that's just my opinion :P
The loading bar showing the progress is really cool, I didn't manage to get the right progress percent on my game because it was loading too fast, nice job.
