I covered fruits of grisaia for its release. Would have written an article about it's kickstarter at the time if I had had a site then.

The reason it's not been promoted is due to how successful the kickstarter was, it's common for developers to only market their KS and if it does well do little else. They already secured a sizeable amount of profit for doing nothing more than a TS that was available for free, why bother trying to market to the IGN crowd who won't buy it anyway?
