Full Multris update
Read the full published notes in a cleaner layout. The original post stays linked below.
New Features
Added a CUSTOM mode
In CUSTOM mode, the rules are the same as MULTRIS mode except that the player can select the maximum possible size for a piece.
Gameplay Changes
Pieces now rotate around a center point rather than always being re-drawn from the top left when rotating
This allows T-Spins to now be possible
Pieces will now push themselves off of walls (wall kicks) if a rotation would otherwise place them into a wall or existing piece.
This can be leverage to place pieces into holes that would otherwise be impossible without wall kicks.
Visual Changes
WALL sprites and BLOCK sprites have both been updated to look much better
Bug Fixes
Scores above 999999 are now properly supported
Fixed a bug in which the piece generation algorithm was running in the background constantly during gameplay.
Fixed bug with textures disappearing after resizing window on Windows.
Technical Changes
There are no longer any static arrays in the code that have a dynamic size calculated at runtime.
Switched to using the SDL memory allocation functions.
