Scribblenauts Unlimited is coming to Windows, reports Polygon, saying the PC edition of 5th Cell's action/puzzle game will use Steamworks to distribute user-created content (thanks loonyboi). They offer some first-hand impressions of this version and its new interface:

Using the keyboard to quickly type in all those commands, Aubert was able to burn through the in-game event, which bundles a series of quests into a larger goal. 5th Cell promises more than 300 puzzles throughout the game.

Currently, the PC version of Scribblenauts Unlimited supports two control schemes: WASD movement for Max and click-to-move control with the mouse, similar to the tap-to-move scheme of previous Scribblenauts titles on Nintendo DS and iOS.

5th Cell confirmed during our demo that the Steam version of Unlimited will feature Steam achievements in addition to sharing of objects via Steam Workshop. But Slaczka declined to confirm whether Scribblenauts Unlimited would include any Team Fortress 2 goodies (or vice versa).
