I really like it! A bite sized dream like exploration that balances its unsettling vibes without becoming overbearing.
The use of a clock as the UI element gave "I'm late for class" feelings which is perfect considering it's such a common dream archetype.
At a certain point, the wandering became a bit tricky to know where to go. However, that was a perfectly valid way of expressing the surreal setting, which was established very well with your use of blended tilesets. Great job!
