Really enjoyed the atmosphere you created, had a good time exploring too!
I just think you could make that center clock a safe zone, so that no hazzard would harm you in there. I died instantly after respawning due to that. It felt a little unfair. :/
And I couldnt understand what was with the stars, tryed to collect it a lot hahah.
Lastly I think that when you collect the gems it should be gems stored on the UI or vice-versa. I was trying to find the keys and felt strange when discovered that the gems where the actual keys.
Overall it was very good!
