Implement the "take off" animation2026-03-23T22:59:26ZMiquel Sabaté Solàmssola@mssola.com2026-03-23T22:59:26Zurn:sha1:0c9b0ad7938e2ba7e994574b4947e25c82440b8c
This is the animation that is done after clearing a stage. Moreover, and
for the first time since I started development, now we can move into the
next level as intended from the game's design.

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.
