This is a coin that appears after going through a first cycle of levels
and that allows the player to get a different game over screen than
usual.

Implement falling items2026-03-13T21:33:38ZMiquel Sabaté Solàmssola@mssola.com2026-03-13T21:33:38Zurn:sha1:cf3a0c963225068b6e3269f50e240950607a5c6b
Every now and then an item will fall and, as in the original game, a
fuel tank will be delivered whenever needed. There are still some things
left out for later changes, like picking up items mid-air, or background
effects for the rocket being filled with fuel.

Initial implementation for items2026-03-11T22:44:13ZMiquel Sabaté Solàmssola@mssola.com2026-03-11T22:44:13Zurn:sha1:9ae51a4c210b8f01718e21eda592c498715a642b
This now only supports the appearance of shuttle parts and the fact that
the player can collect them at a very specific order and drop them so to
stack up the final shuttle.
This is of course just the skeleton and there's a bunch of TODO's left.

This allows enemies to be even more varied when it comes to the color.

The address sanitizer from nasm provides quite a few goodies, so let's
adapt the code more to it to benefit from those.

During other transitions like game over and such it might also be needed
to have something similar, but for now this should cut it.

Add a title and a main screens2025-03-13T21:52:49ZMiquel Sabaté Solàmikisabate@gmail.com2025-03-13T21:52:49Zurn:sha1:9ff2033e936689135210989a5fee057a4a13527e
This commit adds the skeleton for having a title and a main screen. For
now the title menu doesn't do much, as the selection is simply ignored,
but at least it already knows how to cycle between these two states.
