One of the best games I found here, great job! Love it.
I was surprised by many things like Marie-Anne true nature. A lot of potential here, keep a good work!
BTW: it's normal that in Act 3 I can't get off my cave at all, then it appear one time so I go and see Mina (because I didn't get her earlier), the scene is there and she leave (without showing me cave because I already have one) and then she never appear again and I can't leave my cave again till the end? (also it's even possible to get Mina when you have different cave than the one she show you?).
