Looks like that the game uses some (2) sounds from "Double Dragon". One is the sound, when the protagonist is hit (errg!), which is the same sound when an enemy dies in Double Dragon. The other sound is when the hero hits an enemy (trxt!!).
The boss at the start of the 2nd stage was a rip of Karnov in "Bad Dudes vs. Dragonninja".
