Ok...the first thing I've done is removed the Torn World. No, the Torn World will not be included in Pokemon Blue Chrome, but it is replaced by something bigger and better. The Hygiene system has been incorporated as an absolute MUST. There is no way around it, and the player must follow their player's various needs. This is essential for the next part.
I've introduced multiple new items into the game. The most significant ones are the Dark and Light orb (see screenshot below). Across all the regions, little crystals are scattered (credit to SpriterK for the tiles), these tiles when energized with the Dark orb will transport you into a parallel world to the one you were just in. This is the Dark World. The Dark World will have great significance to the game play, as most of it's story will be in there. Although this game will have the 4 regions, there will be a new story, one never played before. Now the problem with the Dark World is that its atmosphere is highly Toxic. This means that staying in the Dark World will do damage to both the player, and the player's Pokemon. If exposed to its atmosphere for too long, your Pokemon can faint and so can the Player. If the player faints in the Dark World, you will not be sent to the nearest Pokemon Centre since there isn't any in the Dark World, and it will be game over. By game over I mean that you will need to start from your last saving point.
Most of you will think this is terrible - well it is. But there is a way around this problem. Around the Dark World, there will be even smaller crystals scattered across more of it's landscape. These will provide Light protection to the player. This means that the toxic atmosphere will not damage you, and instead, the light atmosphere will make you and your Pokemon regain some energy. Be warned that you gain less energy than you loose though. Further in the game, you will be able to obtain the Light Amulet, which will provide constant protection, which will also allow you to access certain regions.
I will reveal more information about the Dark World soon enough once I get few things finished but here are the screenshots for now.
