Aladdin must make his way through several levels based on locations from the movie. You start from the streets and rooftops of Agrabah, then through the Cave of Wonders and the Sultan's dungeon to the final confrontation in Grand Vizier Jafar's palace. The game follows the storyline, so if you haven't seen the movie you can still enjoy the game! In order to advance to a next level, you must find a key and then go straight to the exit door found in another place. The game has plenty of action and dash scenes and mostly involves killing enemies with basic swordplay and jumping across ledges and rooftops! There are several other dangers around such as jumping barrels, falling objects and deadly pots too to encounter. Enemies vary from Sultan's guards to angry animals. Apart of his sword, Aladdin can collect apples (!) and throw them to his enemies making them dizzy for a short time! Gems can be also collected and traded with scattered merchants for extra lives. Note that Aladdin can also get through some bonus stages by collecting Genie or Abu icons during his quest (Genie offers a bonus stage played with apples and gems, while in Abu he controls a little monkey to collect bonuses falling from the sky!).
Overall, the game found to be pretty difficult as it may easily get frustrating when jumping over hundreds of platforms and rooftops in order to find that key. You may easily fall and start all over again climbing etc. Fortunately you got unlimited continuous and there are even several checkpoints to start. Other than its difficult though, the game is a real gem for any video-game console and micro-computer being released!
Aladdin offers some great background graphics directly from the original cartoon-movie along with some nicely detailed, smooth-moving sprites. The characters are large and nicely animated which makes it one of the most visually attractive games for the Sega Game Gear.
Sound is great too, with tunes taken straight from the movie along with some catchy SFX during gameplay.
