Very interesting concept, I've never tried an active clicker before. It was confusing to have all these different mechanics, with none of them really explained until a random ability unlock. Initially thought the heartbeat sound meant they were waking up and I had to slow down until they cool off, and thought the rain noise was just atmosphere and wasn't changing. Lead to some satisfying ohhhh moments when you realize how it works though.
For some mechanical suggestions, an offset to the + currency graphic would be nice. I had items that added more sleep time, something that doubled the sleep time applications, and something that gave pleasure when sleep time is added. So I had multiple +11's on top of each other and I wasn't sure how many there actually was. Also, some sort of signal when those timing abilities activate would be nice. Kept pulling out too early and missing my bonus QwQ.
