Moving through walls

[nsajko]

It's possible to push the Hermit out of the house with the fire
extinguisher, which could be quite off-putting to new players.
Although I think that's probably very hard to fix.

That's because object collision is tested per-frame, the issue exists in the original Notrium too. Extremely fast moves can make objects "hop" through solid objects, and this becomes easier if the game isn't running smoothly due to the lack of performance.

It may not be so easy to fix, but it sure would be great.
