;Task:
Create a complete but CLI-controlled maze-game!
Use the CLI interface only. The symbols:
1. The hero: @
2. Strong monsters: * (they can kill you).
3. Weak monsters: . (You can kill them).
4. Treasure: $
5. Wall: X
6. Bomb: b
7. Revolving door: -o-
and:
|<br>
o<br>
|<br>
(the monsters are stupid, they can't use these doors)

Maze game.
The object of the game is to get all the treasures. The symbol of the treasure is the \$ sign.
Help (display this text): press ? or h
Exit: press Esc or q
You can detonate a bomb by pressing b, but only as long as your bomb remains.
A bomb destroys every wall around the player (the outermost, framing of the maze
except for its walls), but it won't kill monsters.
The bomb does not destroy diagonally, only vertically and horizontally.
The bomb will not destroy the doors or the treasure.
You can also find bombs in the maze, represented by the letter b. If you step on them,
you get the bomb with it, so that the number of your bombs increases for later use.
The game ends when you have acquired all the treasures.
The maze has not only walls but also revolving doors.
The revolving door, if horizontal, looks like this: -o-
If vertical, like this:
|
o
|
The center of the revolving door is represented by the character o, the wings by the line.
The revolving door can be rotated if you move into a door wing in the right direction with
your character, as long as nothing stands in the way of door rotation.
The player is represented by @ in the game, and his starting point is always in the lower left corner.
There is a possibility of a little cheating in the game: each press of the letter c increases the
number of remaining bombs by one.
(This help screen closes after 10 seconds.)

Maze game.
The object of the game is to get all the treasures. The symbol of the treasure is the $ sign.
Help (display this text): press ? or h
Exit: press Esc or q
You can detonate a bomb by pressing b, but only as long as your bomb remains.
A bomb destroys every wall around the player (the outermost, framing of the maze
except for its walls), but it won't kill monsters.
The bomb does not destroy diagonally, only vertically and horizontally.
The bomb will not destroy the doors or the treasure.
You can also find bombs in the maze, represented by the letter b. If you step on them,
you got the bomb with it, that is, the number of your bombs increases, for later use.
The game ends when you have acquired all the treasures.
The maze has not only walls but also revolving doors.
The revolving door, if horizontal, looks like this: -o-
If vertical, like this:
|
o
|
The center of the revolving door is represented by the character o, the wings by the line.
The revolving door can be rotated if you take your wing in the right direction with your character,
and if nothing stands in the way of rotation.
The player is represented by @ in the game, and his starting point is always in the lower left corner.
There is a possibility of a little cheating in the game: each press of the letter c is one increases
the amount of your bombs.

Maze game.
The object of the game is to get all the treasures. The symbol of the treasure is the $ sign.
Help (display this text): press ? or h
Exit: press Esc or q
You can detonate a bomb by pressing b, but only as long as your bomb remains.
A bomb destroys every wall around the player (the outermost, framing of the maze
except for its walls), but it won't kill monsters.
The bomb does not destroy diagonally, only vertically and horizontally.
The bomb will not destroy the doors or the treasure.
You can also find bombs in the maze, represented by the letter b. If you step on them,
you got the bomb with it, that is, the number of your bombs increases, for later use.
The game ends when you have acquired all the treasures.
The maze has not only walls but also revolving doors.
The revolving door, if horizontal, looks like this: -o-
If vertical, like this:
|
o
|
The center of the revolving door is represented by the character o, the wings by the line.
The revolving door can be rotated if you take your wing in the right direction with your character,
and if nothing stands in the way of rotation.
The player is represented by @ in the game, and his starting point is always in the lower left corner.
There is a possibility of a little cheating in the game: each press of the letter c is one increases
the amount of your bombs.

Maze game.
The object of the game is to get all the treasures. The symbol of the treasure is the $ sign.
Help (display this text): press ? or h
Exit: press Esc or q
You can detonate a bomb by pressing b, but only as long as your bomb remains.
A bomb destroys every wall around the player (the outermost, framing of the maze
except for its walls), but it won't kill monsters.
The bomb does not destroy diagonally, only vertically and horizontally.
The bomb will not destroy the doors or the treasure.
You can also find bombs in the maze, represented by the letter b. If you step on them,
you got the bomb with it, that is, the number of your bombs increases, for later use.
The game ends when you have acquired all the treasures.
The maze has not only walls but also revolving doors.
The revolving door, if horizontal, looks like this: -o-
If vertical, like this:
|
o
|
The center of the revolving door is represented by the character o, the wings by the line.
The revolving door can be rotated if you take your wing in the right direction with your character,
and if nothing stands in the way of rotation.
The player is represented by @ in the game, and his starting point is always in the lower left corner.
There is a possibility of a little cheating in the game: each press of the letter c increases by one
the amount of your bombs.
