Chain Reaction - the first video game I've EVER played! :)

Here it is, Chain Reaction, the first video game I've EVER played! :)

I remember getting home from school when I was 6 (maybe 7?) years old and my sister was playing this game on a ZX Spectrum 48k! :)

I don't think I had ever seen a video game before, so it was a REALLY big deal for me to find this game a few months ago, when I asked one of the Spectrum Facebook groups about "popular isometric games on the Spectrum"!
