Choosing a learning Topic

I like the topic I choose for a side scrolling game because the energy drink is suppose to help you out with energy , in the game the energy drink will do that but after that the player will have a big drop in strength . All the other objects will also give you a boost like the energy drink but will not have such a big drop in speed .I would use mechanics like moving and dodging objects to make the game harder and easier .When the player gets a energy drink the bar on the side will get a big boost but after the boost the player will be barely able to move . But with the other objects that would not happen and the bar would stay full . That's were the player is going to learn that energy drinks will give you energy but in the long run just hurts you .
