Movement is not smooth on high-end devices

[richard]

Because the current world tick rate is 15 TPS, higher-end devices can notice when the snake is updated with the new position every tick. Changing it to 20 TPS and perhaps increasing the spring's mass and friction should aid in making movement appear smooth.

While a recording of this issue cannot be provided, the effect is noticeable if playing the game with a frame-rate higher than 60.

This issue is low priority and only affects users with a high frame-rate.
