WASD Movement
Can movement be implemented using WASD instead of the mouse-clicking?
With the inherent re-draw choppiness, mouse-clicking can lead to undesirable results, especially with the chip-races, once you get about halfway through the chip collection.
Having WASD would allow more fine control.
There's a two effective ways to do it, either each button-tap enters a queue of squares to travel, --or-- the game looks for what button is pressed once a certain portion of the distance to the next destination square is achieved (maybe 100%, but preferably about halfway through the movement, it starts to look for the next command, and implements the LAST command received after 100% of the movement is completed). This gives a window for the player to give the next movement command, allows walking to be more fluid, and allows the camera to anticipate which direction the player is moving towards, and pan ahead to show more of the upcoming terrain.
