Space Dude

TIn Space Dude, you play the title character, a cosmic who must defend the Golden City from the attacks of King Dorf and his army of Hoppers. To save the city, Space Dude must destroy the advancing Hoppers and battle King Dorf in his mothership. There are three ways to destroy hoppers: attacking directly, building and manning a defense post, and capturing one hopper to attack another. Before each attack, Space Dude must evade missiles or alien creatures to get to the attack point. During each attack, Space Dude is required to blast a Hopper multiple times to destroy it.
