The "HD" DLC is an add-on for the game Kunoichi Trainer that doubles the size of the images. Instead of the standard resolution of 1280x720, a new resolution of 2560x1400 will be used, which improves the game's graphics and makes it more colorful and detailed. This is especially noticeable when playing in full-screen mode on a PC.
Thanks to this add-on you can enjoy more vivid graphics during the game. Each element will have more detail and a clearer outline. Images and textures look more realistic and the game world feels more alive.
