Gigatron This is awesome man!
Suggestions just from a quick look at it:
1) More ability to customize controls maybe? Maybe not that important of what key does what but more like, changing the acceleration speed or turn speed, so maybe we can make the car "drift"
2) Is there some good way or size you suggest for adding or editing images to work with it?
3) More settings like collision effect on slow down, off the road effect, etc
Awesome job so far though!
1 :The control keys are: ASDW or Arrows keys;
Drift effect can be done with adding car sprite this mean you must draw all drift sprite movements and i will try to implement it.
2: you can make your own sprites or background with changing sprites and background.png by respecting all size;
all sprites were defined x,y to x+width,y+height ..
3. Meditating ......
