(The Multiworm actually takes up 2 times 2 squares when in diagonal position)

The Multiworms can move after they clip through a wall or a doorway, then my Agents can shoot them as usual. One solution to this can be to force a Multiworm to be only one square in size when they turn their body close to a wall (compacting it against the wall), and they should not be able to turn their body when standing in a doorway.

Edit: I am considering that the Multiworm can be compacted even in doorways when they turn their body diagonally like the picture in my post. It would be a smart solution to make the Multiworm work as an accordion 🪗. When turning their body so that their tail clips through a wall or an object it would then be forced into a compact version of itself (squished together into only one square to avoid clipping). This would require new sprites of the Multiworm in it's compacted form.
