- the application simulates behaviour of patient snakes
- each snake moves either horizontally or vertically across the rectangular board
- each snake has its own constant speed value and colour (speed values and colours may differ among all snakes)
- snake extends its length by one field every ten moves it makes, although it cannot exceed a length limit defined in your application
- snakes wrap around the edges of the board
- whenever any snake tries to move on an occupied field it waits until that field becomes free
- 'A' key - add a new snake (choose a speed value, colour and direction of movement and place it on a board). Initial length is equal to one field
- 'D' key - remove the most recently added snake
- rectangular, nonresizable window representing a board with equal number of rows and columns
- actual number of snakes displayed in the caption bar
- two snakes can never occupy the same field at the same time
- it is acceptible that horizontal snakes move only from left to right and vertical snakes from top to bottom
