Arcade Game Designer is a tool for creating ZX Spectrum games. In fact, it's the tool we'd all have given our right arms for in the 1980s. Create blocks, sprites and screens, knock out a few lines of code (far simpler than ZX BASIC and numerous coding templates are included) and create a game that would have graced any software house's catalogue back in the day. A few bugs, but this is the tool you wanted when you were a kid. Dozens of games have been written with this tool. Free to download with no obligations, I really don't want your money. However, if you absolutely insist on buying me a pint I won't object.
