I played this game in one sitting, and I honestly would recommend it.
The art style was amazing, props to you or whoever designed them as it's really well done and fits with the game. I also personally love it every time I hear Louis's voiceline on how he never signed up for this.
The writing was also great. It's actually somewhat disappointing how short this was, because I really got attached. You managed to develop Ishara's character to a sufficient amount in a short amount of time, and congratulations for that.
In spite of all this, there is still one complaint I have about the game: the battle system. I didn't particularly enjoy the occasions I had to go to battle, and much preferred following the story line. It wasn't a very exciting system, and the only thing I can really compliment it on is the amazing voice lines in it.
I guess to conclude this, I think it's a great game. The battles weren't that exciting, but I can give that up as it didn't make a huge part of the game, and the story was too engaging and well-written for me to have major qualms. As the commentor below me stated, I think it'd be great if you make a second game. Maybe make it longer too, I'd love to spend a couple more hours with this story :)
