First release

The Game is fully playable but some customization features are not available yet.

• You can only change the map size and the win length from within the code.
• The player amount can be changed when playing online multiplayer - in hotseat-mode you can't change the player count.
• There are many keybinds to make the game easier to play

Keybinds:
WASD - rotate the 3D visualisation (cube)
Q/+ - Move up by one layer
E/- - Move down by one layer
R - Reset the game to the beginning
SPACE - Reset the camera to the standard rotation
Arrow keys - Move the cube around x and y axis
./, - Move the cube around z axis (zoom in and out)
NumPad 1-9 - Place marks in the upper left 3x3 field
