Wonderland

Wonderland is a computer text-driven adventure game developed by Magnetic Scrolls and published in 1990 by Virgin Games.

Wonderland is based on Lewis Carroll's classic children's book Alice in Wonderland, with the player taking on the role of Alice.

With this game, Magnetic Scrolls introduced a bespoke windowing system dubbed "Magnetic Windows". The player's inventory, the location's graphic, the map and so on are all in separate windows that can be moved and resized independently. (Note that a similar system is used in unrelated adventure games like Deja Vu.) The developers stated they believed it would make the game more accessible, giving it a much wider appeal.
