Donkey Kong (Game Boy)

Donkey Kong (also known as Game Boy Donkey Kong in the game) is a Game Boy game released in 1994. The game is partly a remake of the original Donkey Kong arcade game, and the first four stages of this game are the same as the stages found in the arcade game. In addition, however, Donkey Kong has another 97 stages for the player to beat, making it more than an enhanced remake of the original game. Donkey Kong also was the first game in the Mario series to support colored graphics when played on the Super Game Boy peripheal of the Super Nintendo.

Story
The player takes the role of Mario, who is a construction worker instead of a plumber in this game. The giant ape Donkey Kong kidnaps Mario's girlfriend Pauline, and carries her of to a construction site. Mario follows him up to the highest point and makes Donkey Kong fall of the platforms by pulling out the rivets on a height of 100m. But Donkey Kong stands up again, takes Pauline and escapes with her into Big-City. Mario pursuits the two.

What follows is a chase throughout many different locations. Mario fights and defeats Donkey Kong at the end of each world, but Donkey Kong always stands up again and takes Pauline to the next location. Donkey Kong is aided by many of his friends as well as his son Donkey Kong Jr. who try to hinder Mario's progress. In the end, Donkey Kong escapes to the Tower in Rocky-Valley, where he and Mario have a confrontation on the top. After being defeated for the first time, Donkey Kong falls off the tower, but he then takes many Super Mushrooms to gain a giant size. Mario faces the Giant Donkey Kong in the final battle. After the ape's final defeat, Mario and Pauline are reunited and the credits roll. The ending of the game shows Mario, Pauline, Donkey Kong and Donkey Kong Jr. posing in front of Rocky-Valley for a holiday photo.

Level Progression
The game starts out with four relatively simple levels that Mario must scale in order to reach Pauline. These four levels are identical to the original Donkey Kong arcade game. After reaching the top of the structure, Donkey Kong flees with Pauline into the city and beyond. The rest of the game's stages are divided between regular puzzle levels as well as more showdowns with Donkey Kong.

Each world has a varying amount of puzzle levels in which Mario needs to work against time to bring a key to a door to unlock it, thus advancing to the next level. The puzzles consist of building platforms and ladders and using them before they disappear, flipping switches, jumping on moving platforms, avoiding enemies and utilizing conveyor belts. Sometimes, Donkey Kong Jr. will get in Mario's way by flipping switches or throwing poisonous mushrooms at him to shrink him. All puzzles require the player to carefully time jumps and pay attention to the physics of the game - Donkey Kong thus is a cross between a platformer and a puzzle game.

As well as the puzzle levels, each world has at least two battles with Donkey Kong; one takes place part-way through the stage, and involves Mario reaching Pauline while avoiding the debris falling on him as Donkey Kong causes an impact. The second takes place at the end of each stage, and involves avoiding the barrels or other objects that Donkey Kong throws at Mario, picking them up and throwing them back at him. After beating a Donkey Kong boss level, there is a short cutscene of Mario chasing Donkey Kong while showing off how to do a special move in the game to the player. The player also gets one extra life for every 100 seconds of time left he or she had for the previous four levels, rounded up.

Each stage has a regular time limit in which it has to be beaten. It also keeps track of high scores for each level. Whether the player made a new record or not is indicated on the Stage Clear screen after a Donkey Kong boss fight. The current high scores can also be viewed by pressing Start or Select.

In the final 'Tower' stage, each level consists of chasing Donkey Kong and Donkey Kong Jr. to the top of the tower, avoiding their attacks, eventually trapping Junior in a cage, and defeating a giant Donkey Kong in the final battle.

Mini-games
There are also three items left behind by Pauline in each puzzle level - a parasol, a hat and a bag. Picking all three up before finishing the level will unlock a bonus mini-game in which the player can pick up extra lives. In the wheel of fortune mini-game, all the player has to do is to press A to stop the wheel to gain either 1, 2 or, in later worlds, 3 lives. It is not possible to lose in the wheel of fortune.

In the slot-machine mini-game, the player has to press A three times to stop each reel of the slot machine. The icons appearing on the reels are Mario, Donkey Kong, Pauline's hat, a hammer, and a Fire. Mario gains lives for getting one of the following combinations:

Basic Controls
Mario is controlled with the D-Pad. The physics in Donkey Kong are vastly different to those found in the Super Mario Bros. series. The player can jump with the A button. Mario's jump allows him to jump on enemies, but it does not go up considerably high. When falling farther then his jump height, Mario does a somersault which gives him a little bit of momentum. If he lands on a small platform, that little momentum can cause him to fall off. If he falls even farther, he dies when hitting the ground.

Mario only has one hit point. While he is carrying any item, object or enemy, however, he cannot die. If he gets hit, he will instead drop the item and be invulnerable for a short amount of time. This can save Mario for most kinds of impending deaths - he will even survive spikes with it. If he falls too far, however, he will drop the item in mid-air.

Enemies
Donkey Kong features the enemies from the original arcade game Donkey Kong and many individual enemies of its own that are only found in this game. It does not feature any enemies from the Super Mario Bros. series. Many enemies in the game have a different appearance, but the exact same behaviour. The appearance usually depends on the current world.

Objects and Obstacles

 * Barrel - Donkey Kong throws barrels at Mario. He has to avoid them, and can also pick them up if they hit the ground. Barrels can be stopped falling by kicking against them in handstand position.
 * Cannon - They fire bullets at Mario that kill him, and cannot be defeated.
 * Cement Pie - As in the original arcade game, they kill Mario if he runs into one.
 * Conveyor belt - Conveyor belts move Mario and any other object such as the key into a certain direction. The direction of conveyor belts can be manipulated by Donkey Kong or via levers.
 * Elevators - They allow Mario to get up or down. As falling too far kills Mario in the game, using them to get downwards is required on several occassions. Levers can change their direction.
 * Jack - They are thrown by Donkey Kong in 75m and kill Mario if he gets hit by one.
 * Ladder - Ladders are used to climb upwards. Several ladders in the game open and close at certain time intervals or when Donkey Kong hits the ground with his fist. While they are closed, Mario cannot go upwards on them.
 * Lever - Levers have many different effects in the game. They can make Roads and Ladders appear disappear as well as open doors, and change the direction of conveyor belts and elevators.
 * Locked Door - Mario progresses to the next level if he takes the key to it. In several levels, multiple locked doors appear, but only the one from which Pauline is seen screaming will actually open. In other levels, the locked door is hidden in the wall and the player has to remember its position.
 * Oil Drum - As in the original arcade game, they spawn Fires.
 * Rope - Ropes return from Donkey Kong Jr. Mario can climb up and down on them, and he clims faster if he can hold onto a rope with each of his hands.
 * Moving platform - They move around in fixed patterns at different speeds. Their direction can be changed with a lever.
 * Spring - They are stationary and give Mario a jump boost when he lands on one.

Influence on Later Games
Ten years later, a successor to Donkey Kong , called Mario vs Donkey Kong was released. It reused many gameplay elements from its predecessor, such as:
 * The basic moveset, such as the ability to use handstands, kick items, etc.
 * Having to find keys to open locked doors.
 * Many enemies from Doney Kong '94 made a return.
 * The concept of collecting three certain items to access a bonus stage.
 * Boss battles against Donkey Kong at the end of each world.

Trivia
