Jackson please refer to the next thought:
After thinking about scribblenauts over and over again, i think something may be work out to make the game more challenging, if so.
I know you already think The game is already done, we don't have time for that till release, but im just suggesting
There should be a challenge where you canno't remove your creations after conjuring them...
Why? because to kill someone you can spawn a T-Rex, and then after you killed that person you can just remove the T-Rex, and the challenge isn't really working with the real thinking, and is that how you kill that T-Rex that you summoned, that way, people will need to think about it all, not about Luckily thinking about something that kills a Lion like Medusa, but then the Medusa won't be a challenge to the player cus he can just Drag and drop her into the Can.
Another example: There may be a switch that controls 2 doors, in one side stands our hero, Maxwell, in the other side of the doors lies the starite.
The switch is near the place where Maxwell starts, and by default, The door near the Starite is opened, and the door near Maxwell is closed, after standing on the ground switch / puting a box on it, the switch activates and the door near maxwell is opened, but the door near the starite is closed, now because what i have said in start, you can just remove the box and the door will open, its not that challanging is it? but if you couldn't remove the box, you have to think about how to destroy the box! or make a Dog that stands on it, and after crossing the first door, you can summon Cat/Meat so he will move off that button, and thats more challanging, isn't it?
Please refer to this, took me alot time to think of.
