An interesting experiment in UX. I liked how the audio told me the pieces were 'working' and progress was being made. It made the inputs feel really satisfying when put alongside the visual feedback.
I felt the story could've been less misty and random - maybe a direct goal instead of a series of short vignets which had no importance to the next.
The text was satisfying and I felt it moved at the right speed. Maybe a persistent title element for each room would've made it feel less ephemeral and given an idea of where the player was at any one time.
The combat had a fun layout. I expect it would be more fun with some sort of inventory system.
I look forward to seeing where this goes. As an experiment it made me interested in the author's other work, and I definitely need to make short experiments like this myself. Looks really good in the portfolio.
