First, I loved the reference to Konosuba ! In view of your notes, i was expected to see horror elements early but i was pleasantly surprised to don't see this yet(except for the introduction scene) and that's nice for me that you take your time to introduce the characters without going too fast in the horror elements.
(Also, i love rewatch the first conversation between Xzav and Varion idk why but i think just that the reactions of Xzav are really enjoying to see.) Btw, like said Offlinewolf, the characters change expression mid-dialogue adds value to this game and helps to make it unique according to me. That's really a good idea that you had here !
I'm looking forward for the next update ! But, obviously, take your time ! (sorry for my mistakes, that's my first feeback in a foreign language.)
