I enjoyed solving the riddles to get access to a passcode for the door. I can see how it fits the theme of "What's behind the door?" by solving the riddles.
However, being thrown into a maze afterward was a bit of a whiplash. I was pretty much stuck in the maze for a good while, and I got bored instantly.
What can be improved:
- Sounds - some background music or interactive sounds will feel nice.
- For the maze segment, I recommend giving the player a way to mark where they have been. It gives the player more control and encourages them to explore.
- A hint system would be nice for those who need a little help in solving riddles.
Good job with what you did for a week!
