Yep, helpcomputer0 was the main inspiration here. As for the motivation - I've noticed that only three weeks were left before the start of CAFe 2022 demoparty, so I decided to participate in it and made it in a day or so.
Great work Grongy! Reminds me of the pieces done by helpcomputer0. Where you inspired by their own work? If not, what motivated you to do this ZX Spectrum piece?
That's awesome. Once again,your work is great. And thanks so much for the reply!
