I'm glad you're enjoying the game! :) As for similar games, I'm afraid I'm a little out of the loop these days (after working all day on adult VNs I don't usually feel like playing more in my free time!) but I hear very good things about "A House in the Rift", and of course the classics like Harem Hotel and Mythic Manor. "What a Legend" is also amazing, and completely hand-drawn.
I'm sure others here can recommend more, and there's a whole list pinned up in the CK Discord of other games people might be interested (plus other devs can link their own games in the #link-sharing channel) :)
