You know, definitely not my thing. I never got the navel thing, most hypno, brain drain etc. But the animation is wonderful, and the art is beautiful. The prose, similarly, for much of the lewd portions do little (the character’s own personality was simply not there, which I guess is the point) and the ending was a total anticlimax for lore (I get it’s supposed to scale the event but SPOILERS immediately downplaying it just felt lame) but everything outside of that was very polished and interesting writing.
Outside of a showcase of beautiful art and animation, I also think most of the puzzles were very well thought out and do great signposting. Even the softlock one. At least, I assume there’s a softlock one, I didn’t want to trigger it.
My only suggestion? Animation showcase, like the lewder games this is inspired from. That way anyone can view the anims/scenes without savescummin’. Unless that’s already a thing and I didn’t see it, lol.
