Attack of the Thought Weevils

Created for the Minimalist TTRPG Jam 4. Follows the "nightmare" rules of being under a thousand words and not using any tables or lists.

This game can be played with a scrap of paper, a six sided die, and about five minutes of time.

You have been trapped in a featureless room! The only way out is to use your magic pen to draw a door, but before you can do that you need to gather enough magic by drawing other features on the room. Can you escape the room before the thought weevils arrive to eat all your hard work?
