Yankee DO!

Yankee DO! © 1982.

Hack of "Mr. Do!". It has an American theme :
* You control Uncle Sam with a bomb instead of a clown with a snowball.
* Apples are replaced by oil barrels, that when dropped leak out their oil before disappearing.
* The enemies are people riding camels.
* Only freeze your enemies for a few seconds.
* The Letter monsters are accompanied by cars.
* This is the hardest of the Mr. Do! hacks.
* You run faster digging through the dirt than through open terrain.
