I am working on a remake of a popular 3d game called cubefield but in 2d. I have been trying to take an approach with tiles but have realized that many tile based systems are very difficult to work with for this kind of game. Plus it needs to be able to have and infinite amount for the y as cubefield is an infinite game where you try and get as far as possible. It would be nice if it could be in an x and y list separately. If it is not please explain how i could add to specific points on the map.

Thanks,
