Tentacle Dungeon Clicker

Your tentacles run a dungeon now, and the job is milk extraction. Heroines show up as challengers, you drain them, and their breast milk gets converted into magical power. It's a dark fantasy premise played completely straight while everything else about it is a clicker.

The loop is exactly what it sounds like: click to build up your tentacles, use that growth to process more challengers, feed the output back into your power. There's no dungeon-crawling or combat to speak of, just the extraction cycle repeating and scaling as you go. The heroines exist to be broken down into resources and teased along the way, not to carry a story of their own.
