heres some ideas for a sequel:
no longer is it just paper, the main character, doodle, embarks on a new quest to help bring peace to other kingdoms in craftania (my name for the world doodle land takes place in) ala super mario 3! this land is full of crafts like card board, legos and clay, as well as paper. This time there is a new threat, known as the shreddarians from the planet offyce (play on office). they are a bunch of robots with only one goal: to eliminate all paper, and by extension, doodle (ala daleks from doctor who). the shreddarians have invaded craftania and doodle must embark on a quest to stop them. along the way, he will encounter enemies from the first game, along with new ones to fit the material each kingdom is made out of.
This sequel would be slightly more advanced and difficult than the first, that way this could help to give the children more challenge as they get older and are able to understand bigger concepts, such as npcs and puzzles, so it would grow with the children. it would be made to suit the age of the children that are 1 or 2 years older than when they first played, so made for children around 6 to 8.
what do you think?
