I like the symbolism of the hourglass, and I think the idea behind the game is really cool. I wish his sprite changed to reflect his deteriorating condition. I really like the music too, but I feel like I'm only hearing the beginning of the song on loop. If the beat dropped or the melody really started then it would go so hard. I got to 300 seconds before I stopped playing because I didn't think anything new was going to happen.
Also, Godot FTW!
