I loved the aesthetics and mood. Moving around felt a bit janky due to the doors, but it may add to a stressful atmosphere. I think the red ghost attacks way to often, so it became annoying more than scary. I couldn't find the first item to give to the first blue ghost unfortunately, so I became stuck and stopped there. Still a cool experience overall.
Edit : to add, the red ghost's sound was always exactly the same, which got a bit out of the immersion and is part of what got annoying imo. A slight variation would've helped a lot
