Ah yeah, I remember the Double Dragon series from my Amiga. We played those games for hours. Now I dug up a PC version of one of those games and happily I started it up. Hm... now what's this? I guess my memory isn't that good anymore. Your fighting options are somewhat limited, kicking, punching and jumping - aaaalright. Let me tell you - forget about the other options, you get along best with only using your kickjump. Mysteriously your player takes off for one of those and then you can let it kick left and right without him landing - although that proved useful I have never EVER seen someone doing this in real life
Unfortunately the fights often get very stupid - your enemy will knock you down and then wait for you to get up again just to knock you down once again, sometimes it's hard to get back into the game again, especially when there are more than one enemies standing around your unconscious fighter. Of course you can do the same with the enemies you knock down, but you carefully have to knock all enemies down to one spot to keep them under control. Then you just stay there waiting for them to get up again and send them back to sleep with one of your kickjumps. It gets a bit boring after a while.
One of the nicer parts of this game is the background story - you are searching for three mysterious stones and are travelling to many different places - everytime you finish that scene that old man comes up to you telling you some more mysterious things. Well, the surroundings are good, the graphics are really nice for 1990, but as I said above - for a good fighting game your options are just too limited and the need to press 3 keys at the same time to achieve something doesn't really make this a good game. In case you don't find out yourself, the Shift-Key and Return act as Fire-Buttons, pressing them together and indicating the direction with the arrow-keys will make your player perform that kickjump I talked about. Sometimes it could also be a good idea not to walk, but just jump, but that's up to you of course.
