There's now a new preliminary Amstrad CPC conversion, (though it looks pretty finished to me), of Dead by Dawn available, the game I originally made for the ZX Spectrum. You can read more about it and download the Spectrum original by clicking here.
The Amstrad version was converted by Miguel Sky and you can get it by clicking HERE, and then clicking on the download link, (the part that says "Dead by Dawn.zip").
You'll obviously need an Amstrad emulator to play it, but one of those shouldn't be too hard to find.
Here are a few screenshots...
