What tooling to use to start zx spectrum game programming?

[Mad Fritz]

My Russian is a bit rusty after too many years not being forced to use it - is there an English manual by any chance?

A brief English description is here
Complete not found... Ask what is not clear, I will answer (in topic for Pascal)

Thanks a lot, it'a a good starting point. I will give it a try and come back to you if I should stuck (or refresh my Russian).
