This and That

This update contains a few small things I wanted to get out of the way.

• There are three more game over animations. In total there are now four game over animations, which are chosen randomly.

• Additional parameters in the menu for adjusting the distance between camera and field, changing the total visual height of the field and switching between different stretchings of the row heights.

• The text "Mirror" is now in front of the mirror-view (may sound trivial, but actually required an ugly work-around).

• Added sections in the documentation (yes, there actually is an excruciatingly detailed documentation) explaining how the drop-points are calculated and how the lock-delay works.
