1- First one is right at the begining. You go downwards past the park, you'll find this prop at these ruins.
2- I didn't have time to get a screenshot for the the second collision bug, but it's right at the trifurcation with the center path guarded by guards. Head east facing the north wall and you will see a sign on the wall very soon that you can walk over.
Also, at the Party place before the boss fight (not in slut mode), every hyena sitting on a chair facing the stage will be through the seat. I'm afraid you can't fix it, since it is a graphic bug and RPG Maker is... you know.
Finally, a minor spelling mistake at the alleyway with a secret scene in which I really thought I was going to be jumpscared on.
I will try to get prints from the kitsunes once I have sparing time. I tried doing a quick run, but Mahir made sure I got the unluckiest odds:
He did wound up
I guarded
He dazed me
(lost turn)
He striked and one-hit killed me.
That happened Twice in a roll. I'm not sure that is intended, but I didn't have that problem the first few times I fought him. Anyhow, it doesn't give much chance for the player to evict an early game-over.
