This was so tense. Even after seeing the failure ending, my heart still stopped every time the woman showed up. The pixel art and voice acting is phenomenal. Also loved the animations and style a ton! The only difficulty I had was getting lost. I'm guessing that was the intention, but maybe some landmarks would help once the key is found. Needless to say, I had a great time and great work!
My developer brain is curious how it was determined when she showed up. You don't need to share the secret sauce... but I'm guessing random time intervals?
