First, Clair de Lune, oomph. Made my day almost.
I tried to play around but couldn't get to the actual game because there is no single-player option.
But from what I see, and watching the trailer, it's too much for my taste. Can't imagine myself enjoying it without doing a 100-hour training. I am lost even when the hint is in front of me :D
As for technical suggestions;
1) Can hide the cursor when focused on the game since we are using a controller.
2) 0-100 range frame rate option seems a bit unintuitive. I suggest making it fixed numbers like 30-60-unlimited.
3) Also game started with normal framerates then when I changed some menus, it started to stutter. I figured that setting took effect in between and set it to higher.
4) It took a while for me to find my way out of the dictionary menu. It says change mode by holding RT-LT together but it needs to be more clearly worded and to be more on-your-face.
