Creaking Hearts release Wilting Spores

The pale garden is perfect at night, but during the day, it seems a bit empty. I know that was the goal, but there aren't any challenges during the day. I was thinking, since the creaking hearts release a horror at night, why not a challenge during the day? Since the pale garden is, well, pale, I thought why not show the reason why, and that would be the creaking hearts release Wilting Spores during the day. There would be a timer over your hunger bar, similar to the bubble bar when you enter water. It would take much longer to deplete than your bubble bar underwater, but it wouldn't last all day. If you spend too much time in the pale garden during the day and your, "bubble", bar depletes, you will slowly start to lose health. This way, players only really get to explore the pale garden at night. And, if you manage to break every single creaking heart, the spores will stop and the pale garden will turn back to a luscious forest with plants that once long ago bloomed.
