Honestly, the fact you can't play more than once adds to the eerie feeling, as if that world's "Protagonist" permanently died and won't come back. Honestly nice work, and atmosphere. Again, however, slow.
Edit to my previous comment (Yes kong, you need to add the ability to edit your comments): Anything under 10 seconds it seems will be an automatic bronze. So with the 0 Timer glitch, It's still possible to get gold.
Before this glitch was fixed, Restarting in a level would make your time 0. And you could press escape again to start the time, but Now it gives you a bronze for doing it. You can still preform this glitch, only difference is that it'll not give you a Gold.
