I'm thinking of making a game with this sort of gameplay style, but i need an easier way to do so, since my way of re-creating this style would make it more complicated to create.

Actually, couldn't i just copy this sample's code, then cut out what i don't need? Though, i would probably have to make several little tweeks to make it the way i would want it to be, so if anyone would be willing to help me with that, i would be very appreciative.

I guess in theory that would work. But you would need more than just the map data.

I would imagine that you would need the map data, the code that draws the lines, the code that simulates movement, and the code for collision detection (if there is any).

Actually, now that i think about it, i don't know what i would delete, and what i would so this may be a bit more complicated than i first intended...
