Progress on my GTA-ish top-down game

This is an early demo of a project I've been working on. It's supposed to be a top-down game, much like the early GTAs. I've currently got the following things working:
- Loading the map from a file
- Loading and applying textures
- Loading and rendering a bitmap font (debug info)
- Basic player movement (Steering with either arrows or mouse)
- Very basic collision detection
- A simple OpenGL render engine (I might extend this with other non-top-down views)
It's written in C using SDL for cross-platform awesomeness.
This is of course a very basic demo, and nowhere near a finished product. The textures are done as cheaply as possible to show that it's about the game code for now, not about the graphics.

This is awesome Harold, this is quiet a achievement i was think about doing something similar but didn't have the time. GJ

I would _love_ to see the code, but just finding the video (and finding out that you used SDL) has already helped; I think I will go for a Qt5+SDL2 combination attempt to create something similar. Thanks!
