update

i just updated the game, cleaning up alot of code and changing how the game works. i learned alot over the past month and i put as much of that knowledge into octagonis as i could,

• there are now sliders in the pause menu for music and sfx volumes
• changed the layering on the title and game over screen
• made the difficulty increase more as the game goes on
• added 10 new levels
• code reorganized, so more (hopefully) legible source code
• fixed a bug involving the play field rotation
