Grafight

In the Drawing selection screen, the first 6 choices will be player 1's drawings. The next 6 will go to player 2.

Before battle starts, you can only draw whatever drawings you want. Whoever has the first turn will not gain graphite, but afterwards, you will gain 4 graphite at the beginning of your turn. 

During your turn, once you use an action, you cannot spend graphite to draw another drawing until your next turn.

I plan to implement a tutorial very soon, but hopefully this will do for now... Happy drawing!
