Way too basic, I think. The story is way too short and doesn't really have enough of any of the components that make a good visual novel. I couldn't really feel for any of the characters - the main character has no real reasoning behind his actions, so he's just a set of skin that the player puts on and wears. The girl and the main character's friends are generally rotten and selfish without much background to explain their own motives. Moreover, the 'take the bullet' choice is so transient because it doesn't really affect the plot outside of the predictable outcomes of who dies.
I guess it was nice enough that everything wrapped itself up quickly, but there just isn't any artistry here. After 10 minutes of clicking and reading I died twice and got a kiss on the cheek. Seems a little empty if you ask me.
