There are two things that stood out to me:
1. The use the "shadow-sprite" attached to the player at the beginning, to give a quick, fake shadow, it's a nice way to quickly add a bit of atmosphere.
2. The zoom out during the maze section was a good way to build tension and intrigue, along with it being a play on the mechanics of solving a maze.
I'd say focus on these two types of ideas going further with any projects.
One being quick, cheap ways to get interesting, atmospheric visuals (the shadow).
The other being simple, mechanical things you can do to get a changing reaction from the player (the zoom out maze).
Good work, keep at it
