But according to official information, IF has two versions: dark night, white night, and three routes: dark night route, white night route, and hidden DLC third route.

At present, the official pre-sale limit is that a cassette contains two routes +DLC route download codes, and a complete IF game can be obtained through online download.

What's the difference? Different routes, the main characters used, and even the plot are different, and it is estimated that to understand the whole IF plot, we must start from the full version.

If you pay for one version, another version of the route and the hidden third route should be available through DLC payment.
