BBC Interactive Editor Iain Tweedale told DS that the corporation may develop more titles based on the success of the current four-episode run.
"We're talking about it, yeah. Obviously we're seeing how this goes, but we're all very pleased with that," he said.
"It really does depend on how the others do, and what the commissioners think abut what we're going to achieve. It's really about things like bringing in the wider audience as well as the hardcore gaming audience, and we've done some research that suggests we are actually hitting those people, which is great."
Executive producer Charles Cecil added: "I think it would be great to see more. Obviously that's for the BBC to decide, [and] I think probably a little bit more adventurous in terms of the puzzles.
"We went for a very, very broad audience with [the first episodes and] as you know there's been 550,000 downloads, so it's going go for a million probably within a month. So it's been hugely, hugely successful and I think it has really reached all the objectives that the BBC has set it.
"Most of the people who would play a second one would have played the first one so they now know the grammar of how these games work. If we were going to do more, it probably would be a little more tougher in the adventure department. Not contrived, but just a little bit more challenging in that sense."
Second episode Blood Of The Cybermen will be available to download for free in the UK from Saturday.
