Thanks for playing the game! We loved your playthrough and reactions :D There was a specific sound cue to letting you know how much you've progressed through the game. Also, there was a time to how much you had to survive and you could check by pressing F. We posted a recent update identifying when you've lost to make the game a bit less clunky, and a helper text to let you know what to do at the end in case players misinterpreted the game bugging out with a black screen
