This. Is. Brilliant.
I've got all ending but haven't unlock all memories, so ... maybe I'll replay again. Hopefully this time, as a completionist, I can get everything!
Overall, I really like the character design (love the timeglass) and I had this need to hug every one of them. You have succeded. The switch from ADV to NVL style is brilliant. And somehow, renaming all option from its default names made it very special to me.
Great job!
