I honestly thought this was an Adventure Game Studio game by how bang-on you captured the point and click style of games. Absolutely loved it!
Naw, I wasn't alive (or british!) enough to remember the BBC micro, but it looks like an incredibly interesting piece of tech. I remember playing with the incredibly old computer my grandfather had when my dad was younger and you'd have to type in all the game code before playing it. I hope you continue with the 2d point and clicks because you've got such a great and unique style with them - it's surprisingly hard to find good horror point and clicks that aren't just "and then you saw non euclidian geometry and pyramid head kills you!" hahaah
Honestly, it was a bit shit XD but it got me fascinated with art and games on computers. Oh wow, I wonder what that was! Must have been so cool to see the code you typed in turn into a game. Haha, horror can definitely see the same tropes being used time and again. If you haven't played it then I Have No Mouth and I Must Scream is a classic horror point and click like nothing else! I'll come back to 2D again one day, but I have a set of joysticks coming soon so I'll probably make something for them and VR next.
Ahhh it's always better in our memories eh. I have no mouth and I must scream is a classic, but I was definitely too young to play it when I first did, I should go back and revisit it. If you get a chance check out Organ Quarter then - it's a vr horror game that I feel doesn't get talked about enough, and I absolutely love the style of it. You might find it really inspiring!
