OpenGL/C++ prototype game

We need a clean and well commented demo developed latest by the end of tomorrow evening. The time frame of the job is so small because the project has to be demonstrated soon. This is a simple game project being developed as part of a charity for local schools and their kids. The project itself is half developed and simply requires to be finished off. It would be preferable if the developer knows how to use GitExtensions as we have a code repository set up on bitbucket and would prefer if the developers used it as the means of committing code. This way we will be able to keep track of the project. Do apply even if you are not acquainted with bitbucket and Git Extension we will work something out. On the grounds that this project has already been started, and this is quick simple demo as a charitable cause we have a limited financial resource. Please only use open source models (if models are required), attempt to not use external libraries and keep with the house style of the existing code. Document (comment) any changes you make. Please find the project description attached. Due to time constraint we are open to negotiate what is feasible to be implemented.
