Hero is a very stylized game; it's best described as a combination of NES, Atari2600 and C64 games. The graphics are purely black and white, and the game strives to recreate the feeling you had when you first played games like Metroid - you get no map of the game worlds, so you may have to draw your own. It includes six levels, eight MIDI songs sequenced in Jazz++, and some bonus features after you beat the game, including an extra difficult level. The game is rather short, and should only take a few hours to beat, but older people may find that it gives them that familiar retro feel.
I think the game was good. In level 5 it was a little confusing to find the different places since there was no map, but i guess i could just have drawn one.
