- Reward system in Story mode (currently, either credits or random set)
- Rules now accept for player 2 to start (see story mode "block" stage)
- Story mode now has an autosave/autoload mechanism. This is for convenience but also to prevent people from abusing the reward mechanism too easily.
- possibility to choose an avatar for both players through the rules (see example in story mode)
