Port of the GameBoy game Ninja Gaiden Shadow from 1991 converted to the ZXSpectrum in 2018.It was meant to be a GB port of the NES game by Natsume,Shadow of the Ninja,or Yami No Shigotonin Kage for the japanese Famicom,but then Tecmo(The owners of the Ninja Gaiden IP)acquired the publishing rights and requested the game to become a Ninja Gaiden game that acts as a prequel to the first game on the NES.personally i don't like the whole prequel thing.besides,the arcade Ninja Gaiden game was already a prequel i belive,and on top of that,there was yet another prequel to the NES game called Ninja Gaiden X made in 2004 and only released in japan,but that was just a very short mobile game.

Overall i do like this homebrew version.It adds some decent colours to the game,and the way the controls were adapted works fairly well once you get used to it.And there's also a key configuration option,which in my opinion,every spectrum game should have.So yeah,you shouldn't really have any issues to play the game.

Here's some negatives i found though:The input lag from the original game is still present(Yes,the original has input lag)
There is no intro cutscene,and there doesn't appear to be a sound test code like the original version which sucks cause i do like these renditions of the songs,and i would love to listen to them outside of the gameplay so the SFX don't mute the notes of the music being played if you know what i mean.

But despite all of that,it's still something i would recommend,definitely give it a go if you can.And even though it's free,i honestly think that DarkHorace,the person who made the port,should recieve a reward via donations for his effort.
