Not to burst your bubble, but this is nothing like Spineworld. It's just a couple of avatars that you can click around the screen over 3 backgrounds from Spineworld.
The whole point of a remake is to make something very close, if not identical, to the original game. The goal is to capture the gameplay and tone of a game. It's great that you're trying to bring Spineworld back, but I'm afraid there's a long way to go before this is anywhere near what the original was like.
First off, you're going to have to write all the code, not use a chat/game maker. Second, you'll need the avatars, music, quests, houses, everything from the original Spineworld in your game. This is a long-term commitment, and will take tons of time to do. I tried once and failed due to school and whatnot.
If you're really serious about creating a remake, you're going to have to start from scratch and work your way up. It'll take a lot of time, energy, and effort, but in the end it will be worth it.
