Everytime I look at Hiryuu he seems like he's on a mobile phone . It's the way he's holding the clipboard to his face lol, maye a design change is due?
I enjoyed the music throughout, the writing seems sparse in places, some of the male characters hairstyles and bulid look very feminine though, more manly looking perhaps?
The background art has potential and I like the small amount of colour backgrounds so far. I know more writing is needed and this is a work in progress still but please give more character interaction, responses etc.
I would like to see some action screenshots of the monsters though although it is a demo, perhaps in full game. Overall it's a good start, has potential going forward and I look forward to seeing its development and release. Good luck!
