Skyshift, an Amstrad CPC shoot them up by Titan
-One projet of titan was to make a shoot them up as 1942. But he is a graphist and not a programmer (it's not a critic but a fact, as I am a sunday programmer). So he got the help of the IA Claude.
The result is Skyshift (version 1.1) that you can test below or just look at the video made by Xenomorph.
