Impressive atmosphere! I really like the sounds and music, and the action scene at the ending.
I kinda wish I could move in 8 directions, but I got used to it really quick and it didn't bother me much after that.
I also enjoyed the metroidvania aspect of it (seeing places you can't reach initially but getting items and backtracking to be able to). Finding keys was a bit "linear" in the sense that they were all on the "off paths". The woman cutscene is great and I wish there were more, but I can absolutely understand having to prioritize other things because of the time restrictions.
One thing about your games that always makes me want to play them whenever I see you in a game jam is the mood and the audio. They always have a specific "feel" to them that I find great. Good work!
