Medical equipment as new obstacles. Few examples :

- Medical crate.
- Medical operating table.
- Medical robot arm.
- Wall of infirmary.
- Medical computer

Hm... a Medical crate is easy, I think. It is just take a normal crate, paint it
of white, and paint a red cross in middle of it. The others one would require a
bit more of work.

This, however, don't appear too important: The game don't have a hospital. It
only have Doc Moore, who won't have such hospital equipaments. :P

We now could actually have "healing crates" via obstacle triggers; if tux
smashes a healing crate, he gets healed by 50HP or something like that, should
be doable now.

Sounds good. Recoloring the box to white and painting a red cross on it is
enough (That is what a lazy human would do, in game, in real life, and in
development. So it's doable imo).

Well, then I think that us should implement this with healing tux by 50HP. We
just need inform the personal responsible for such things.
