I liked this game a lot! Absolutely loved how you used spatial audio for the clock ticks. Played with headphones and thought that was brilliant!
Unfortunately, I didn't notice that sleeping restarts the current level, and was very frustrated when I was a few levels in, lost, and got reset back to the beginning of the game. Perhaps making it more clear would help (I tried it during the first level and thought sleeping meant restarting the game, so I was too afraid to try it out during the next levels -- didn't want to lose my progress, after all!).
Thanks for sharing! Rated!
