Had this on Sega MD back then and never really liked it that much. Was a bit hard as i was never able to pass level 4. I fired up the sega recently and tryed it again and i still couldnt pass level 4 (showing that my brain still hasnt grown a bit since all thoese years)
Its a nice game to spend some time i guess but i dont have the patience to play as the jumping is a bit hard also if i remember correctly some enemy units had homming star-ish lemon-ish thingys that were almost impossible to run with thoese bulky controls of the game
The main hero reminds me of a poor animated gorilla when he walks and specially when u press the attack button he has a wierd attack animation like this... (does a funny face and some moves with his hands up and down and u people dont see it, such a shame

) He also has a retarded jump that is more like a hop u do to step on an ugly cockroach u just saw infront of the kitchen door that usually makes u fall from platforms or makes u land on snakes and loose health.
