But I also seem to miss the point of some aspects. Like, what does it bring to explore dungeon?
I mean, even killing the boss teleport you into a weird place and then nothing to do there.
at the moment in the dungeon you need to assemble the optimal "build" for the character.
Healing the sister's illness, after opening and activating the functions with milk and killing the boss for pieces of the philosopher's stone, from one of these makes a special potion (a potion, before milk you can't give sister to drink)
And then only get meat for food that will please the sister
Money is only required for milk, or gacha. (the piggy bank at the moment is a separate phase of self-masochism)
Or what's the point of preparing meal?
with the preparation of food so far there are 2 main "benefits".
First: meat gives a buff to the sister so that she does not wake up at night longer. Fulfillment of the "promise" (gives the item "sister's smile", a good item)
Second: not yet fully implemented, is spicy food, after consumption there will be a still not implemented "function", namely "check the mouth"
