Overall, this was pretty good. I liked the story and the idea behind the gameplay and light shards, and loved the the constant chatter during the battles.
The blindness mechanic did get a little tedious after a while though since battles did not drop gold to buy more eyedrops, and the healing/mp items did so little that I felt like I had to hold on to them and not sell them for more eyedrops.
Mapping was pretty good in general, though I did come across a few places where I could walk onto walls or through objects, so that is something to watch out for. Also, walking up to a door from outside went inside, but it required pushing the action button to leave a room, that should be activated by just walking to the door / edge as well.
Also watch your message boxes, there were places where the text went beyond the box so got cut off. Liked the changing expressions in them though.
But still, overall quite enjoyable for a first game.
