Oh my gosh, you have improved so much! There’s lots of detail now in your environments, and you incorporated combat mechanics! Well done!
The hallway still feels quite empty, and without any story or things of interest to occupy it at the moment, I’m not sure why it’s there. Also, be careful with invisible doors, as they are, well, invisible. It can be very easy for a player to get lost if you don’t mark them correctly.
I like the little hints you’re dropping to the big reveal! Can’t wait to see it! 😀
