V1.2 - Minimap & General Improvements

Fixes
Fixed white lines between floor tiles.
Fixed the terminal window not closing when pressing the X.

Minimap
The Minimap shows the current player position, doors, rooms, chests and cores. It always shows the entire map.

Improvements
The catchy music was moved to the titlescreen and got replaced by a more athmospheric tune.
The titlescreen now also has a fadein/fadeout animation.
Changed the UI layout a bit.
Changed the Actionbar to only progress on tap/when pressing Q.
