Dr. Doc is an excellent puzzle-oriented action game that has you collecting items to cure infected Fufflers in each level.
Just pick up the fruits using the CTRL key and throw them into the machine to make potions. Use them to save the creatures. The only feature missing from this freeware is some background music.
