No

It's an Amiga strategy game, though.

Ok...:

Something intelligently named, like Kiss Pinball? 

Sadly the pinball reminded me of the terrible Foucault's Pendulum book

^That was actually good

They are dressed as building materials, but this doesn't ring any bells for me

Argento? 

^_^

Since I only just posted one, I think someone else should do it.

^Is it the PS1 iteration of Clocktower?

As it should. Those games were terrible...

Though at least Jet Set Willy had a larger world and some surreal elements (Roland was a lazy version of that).

Hey, I know that character! That's Roland!
I recognize him as the mascot of Roland Radio. 
And according to that site he's from... either Roland in Space or Roland in Time.
Considering the screenshot, I'm going to guess that it's Roland in Time.

100% correct ^_^

And the music theme of Roland in Time, by Amsoft, seems to have been stolen from Dr. Who.

Not very surprising, when you consider the goon who owned failed computer Amstrad 

I was 8,5 years old when I got an Amstrad CPC6128 with green shades. One year later I got an Amiga, and it felt like I went from the stone age to modernity.

^ No, but close

In fact Jet Set Willy has a very similar style, although it was clearly superior to this game.

This was the first ever game I played in a computer I owned:

I don't think I deserve it - I mean... "Knightmare" isn't that close to "Nightmare", in this context.

But if the others don't want it, I will come up with something in a couple of hours

^I like that guess
