Thank you for playing! I'm sorry, I didn't have time for a number of features I wanted to add like levels with lower difficulty, which included different keyboards..
Yes, so by "stall" I just mean when a car is stationary for any reason. If they're held up by the stop mark, or by a car in front doesn't matter. I wanted to add some visual/ audio feedback for this (like the cars tooting in annoyance or something) but didn't manage it in time. Hopefully the fire system is visual enough that you can realise you are close to losing when all the cars start slowing down again and the fire colours fade away. Thank you for the feedback!
