Firstly I just got to say you made a fun game I really liked it but I did notice a few things.
I noticed a visual bug in Amiya's shop where the top right of the window in which you buy here items is a little obscured by the menu to select which girl will be selling or buying with their essence.
I don't know if I just missed something but I could never find the solution for solving the slime girl in the gym's problem, I walked around the map doing dungeons for a while but I found nothing.
I feel like either certain glyphs should be rebalanced, I often found myself using the base attack glyph for my damage as any combo/mix of items in crafting I found seemed to give little to no varying results in damage (more often resulting a glyph being made with the best items I have on hand having worse stats than the provided set).
I feel like the split glyph was a little strong, it becomes manageable mid-late game but when encountering the slime girls who spam them it became less "I need to put down the correct glyph to counter their attack" and more of "RANDOM BULL**** GO" as I had to simply throw glyphs onto the field in reckless abandon due to the sheer amount of glyphs I then had to counter.
Almost forgot, for some reason certain dungeons on the map like the wolf den have no visual indicator. I would just walk around and stumble upon them as they just look like normal tiles.
Again I still really like the game and I greatly appreciate the effort you put into making it and I greatly await the day I can play more of your game.
