Alpha version!

Alpha version is done with some HUGE additions!

- We figured the best way to incorporate coop with pvp is via a "boss".

• Each boss has a qualification meter, which players have to fill up in order to win the game! 
• Completing the events fills the meter. 
• Winning a round fills the meter.

- The first event is implemented. 

• The conductor ("boss") says a train color that needs to be stopped at the station.
• Players need to remember the color said.
• Players see the train color preview in the background.
• Once the correct color is going by, players need to stop the train by pressing the buttons.

- Character selection added.

• Able to choose between two of the available characters.
