The entire game is rendered with gorgeously drawn backgrounds and expressive characters with well-defined personalities. The art style is very Japanese, with lively facial expressions, great colors, and well drawn interfaces. The RPG scenes, especially, look very authentic.
The only thing of note to really mention is the music, which is very nice and relaxing as you play, but is also not very memorable once you finish.
Alistair is a visual novel with an RPG twist. There are various stats and items which affect your relationships with other characters and the ending of the game. Items are bought at shops, money is made from work, and the way you treat people affects the outcome of the game.
