Oh what's this
It's "Desktop Dungeons", a game based entirely around fighting enemies and getting stronger, and with very short playtimes to boot!

Your turn, show me a game based entirely around being immersed in idling, where players look forward to the dread of doing anything because of the massive amount of time it takes just to start!

Of course, if that's your thing, there's nothing stopping you from enjoying that experience!
Unless for some reason that joy comes from forcing that experience on other people rather than from the experience itself.
