I've changed the victory scene to restart from the TitleScene instead of going directly to the GameScene. Now when the player completes the level and presses SPACE, they'll return to the title screen, and the timer will only start counting when they press SPACE again to actually begin playing.
I've renamed the game from "SUPER MATH BROS." to "SUPER MATH LAND" in the title scene. This was the only location where the game name appeared in the codebase.
