glad it was so easy :)

your turn

Oh-kay, here's a reeeal oldie.

Well that defiantly looks like Miner Willy so Manic Miner or Jet Set Willy, I guess...

Close, but nope.

Well, I guess a little clue is in order: as you may have noticed, the main character is coming out of a phone booth (and no, it's not Dr. Who)

D'Oh I didn't notice you'd called the attachment that!
The only characters, except for Dr Who I associate with telephone boxes are Superman and Bill and Ted and this guy doesn't look much like either of them...

Wow that is one obscure title, took me forever to find.

aaaand...?

I could be wrong, but Roland in Time?

Wow, I thought no one would guess it :)

You're right, of course. I played it a lot back in the day, when the Amstrad CPC game library was really limited; not only it features the time travelling phone booth but it even rips off the DrWho tune in the starting credits:

I don't know why the "Roland" naming, maybe they couldn't get hold of the rights, or perhaps they didn't even try to :)

Anyway, it's your turn.

Roland naming comes from what the Amstrad CPC was codenamed during development. Development name was originally Arnold and the Roland naming is an anagram of that. Just a shame that the character model is so inconsistent throughout all the games he starred in.

Ah an Amstrad exclusive title! No wonder I was struggling!
Apparently 'Roland' was a character Amstrad were trying to make popular at one point, there's another Roland game anyway:

There are loads of Roland games!!

Roland on the Ropes (aka Fred on C64, Speccy etc)
Roland in the Caves
Roland in Space
Roland in Time
Roland on the Run

Few others also

If you head here :

and enter roland in the search box a lot of the games are listed there, I don't believe it is all of them though.

Well I didn't so much guess it as I Google-fu'd it.
Which was still quite difficult, but after a bit I saw which country you were from and I remembered the Amstrad CPC being quite popular in Spain. And I came across an old Dr. Who game that reminded that 'phone booth' is a primarily American term whilst in the UK they used 'phone box'.
Then I had the correct search terms :P
Anyhoo, here's a game I came across whilst searching for 'your' game.

Haha, I know that one too, I really must be an old fart :D

As it has been my turn just before, I won't say it unless no one comes up with the right answer.
Very interesting, I grew up on the 8-Bit era, and although my home computer was a C64, I had a close friend who had an Amstrad, so I have played a lot of those games. I love learning about all that retro stuff, thanks.
