Tents and Trees
puzzle game for Commodore 64, 2020

------------------------------------------------------------------------------
The aim of the game is to place a tent adjacent to each tree in such a way
that the correct number are in each row and column, as shown by the numbers
alongside. When you have the correct number in a particular row or column,
the number will turn green. Tents cannot be placed if there is no tree to the
left, right, above or below.
You can move the flashing selection box around the grid using the joystick,
and place or remove a tent by pressing fire.
As you complete more levels the size of the grid, and therefore the complexity
of the puzzles, increases. The quicker you solve each puzzle, the more points
are added to your score, up to a maximum of 99 per grid. Puzzles are created
using procedural generation so there is an endless number to solve.
