a bit late, but done!
Ok, I am about 10 minutes late. I had to clean up everything bundle into a zip. I only had time for one level, BUT you CAN modify or replace the level. There is a level definition file named level1.txt if you want to peek at it.
INSTRUCTIONS:
arrow keys to move the character.
run across the road avoiding the trucks.
get close enough to the green box, and you win!
