Looks like a decent game. My only nitpick would be the speed of character in platformer mode. It feels off: the char moves rather slow and there are still frames in animation which add even more to the perception of slowness. I would prefer a bit more responsive platforming.
The best part is it's not based on moon logic and all choices are logical. There were times when I've had to peek into a walkthrough, but in the end I just wasn't attentive enough, otherwise it's possible to complete everything without the typical "just click on everything" method. Also, a great part is that every dialogue is voiced over which adds a lot to the overall experience.
I have a discrete GTX 560ti with 1GB memory which is not worse than Intel HD4000 and game runs at 20 FPS at maximum (in the dungeon. it's okay in battle) on minimum settings (other system parts are way ahead of the card, so video card is a bottleneck).
