A side-scrolling game and the genre use by it is platform. I am talking about Sonic Advance. It is similar to the Sega Genesis's Sonic the Hedgehog games. In this game the evil Doctor Eggman have a plan to capture the animals of an island and turn them into robots that are evil. Your mission is to stop him and foil his plan.
There are four characters available for selection and you have to select any one of them. Keep that in mind that every character has its own characteristics which makes them different from other. For example let's start with the Sonic the Hedgehog who have two main features in him which are that he is fastest and protects himself for some time by performing an "insta-shield". Now let's talk about Miles “Tails” Prower and two main features associtated with him. He can fly and swim but for a short amount of time. Now you want to know the features of third character and whose name is Knuckles the Echidna. His three main features which make him unique from others are that he can glide through the air, swim above water but for a short amount of time. Moreover, he can also climb walls. Now you already know the chracteristic of three characters and now you want to know about the last one and whose name is Amy. I am sure female players are happy now because Amy is a female character. Her only characteristic is that she can destroy enemies with the help of her hammer. Amy don't perform spin dash on the ground to gain speed but all other characters perform it. Moreover, Amy also don't defeat enemy robots by jumping and curling into a ball but again other characters can defeat robots by this way.

Don't know the number of levels in the Sonic Advance? I am going to tell you. Their number is six and they are also called zones. Each zone has further two parts called first act and second act. To complete the first act you have to pass a signpost and the second act ends in a boss fight with Dr. Eggman. In the first act your mission is to reach the end by passing through enemies and obstacles. The obstacles included are spikes and bottomless pits. You have ten minutes to finish first act. You can get health by collection of springboards, boost pads, and golden rings. The rings which you collects during game will scatter and disappear in a short amount of time. With the help of rings you can survive hits but you need atleast one ring for this. To get power-ups you need to collect canisters which have them. You have limited number of lives in the game. The losing of lives depend on these conditions and they are "your character get hit with no rings, fall in a bottomless pit, crushed and drowned. Moreover, if the time run out you also lose a live". If the player have no lives left then they can retry the current act if they have any continues left otherwise it is a game over for the player. There are also special springs which you found near the top of certain acts and with the help of them you can access a special stage. In this special stage there are rings which you can collect. You will get Chaos Emerald if you collect enough rings and there total number is seven. There is also a extra boss fight included in the game and to get that you need to collect all seven Chaos Emeralds.
The game also included in it a minigame whose name is Tiny Chao Garden. In this minigame you can raise Chaos. With the help of GameCube versions of Sonic Adventure and Sonic Adventure 2 the tranfer of Chao takes place between the Tiny Chao Garden and the Chao Garden. The game also supports multiplayer mode. Four game's owner compete in searching of Chao or race to the end of level.
