Project 3 Game Proposal

My game is a 2.5D puzzle/action and side scroller game, 2.5D means that the environment and the characters are 3D but at the same time the character may only navigate in a 2D fashion (left, right, up and down).

The goal of the game is for the character to drop objects into the level in order to advance. So every level starts you off with a specific set of building objects, they can range from Boxes to even something crazy like a trampoline, these object also very is size and weight. As the character moves through a level some obstacles appear (Like pits, walls traps etc...) that can only be solved by placing an object into the game world. Here players will be challenged to think about object physics and object form in order to advance.

So the way the game controls is that the character movement is is controlled with the keyboard (A to move left, D to move Right, W to Jump). while the selection and the placement of the objects provided is controlled by the mouse. so the character does not physically have to be at the place where the object is dropped, but the place has to be visible on the screen. So just have to point and click in order to drop an object. Remember that the camera follows the character and not the objects.
Here is a quick sketch of what the game will look like, the object selection is at the top corner of the screen.

So in a way this game is about manipulating your environment in order to get past obstacles in your way. Its hard to actually compare it to any other games. But if I had to compare it with something it would have to be lemmings, lemmings is a game where the game environment had to be manipulated in order to advance, which is kind of what I am aiming at.

I found a video of a game called "Little Big Planet" where the player can drop objects into the game and interact with those objects, which kind of relates back to what I want to do:
