Llamasoft's Jeff Minter has told Eurogamer that his next game, Gridrunner+++, is complete: Microsoft's been "sitting" on its release.
"We sent it off to [Microsoft] months ago, but they've just not said anything - we're just waiting for them," he said.
"Basically I'm going to carry on with the PC version of it if I don't hear from them soon, because they're just sitting on the demo we sent them three or four months ago. We haven't heard a thing."
Minter added that he was disappointed with Space Giraffe's reception on XBLA.
"The thing with Xbox Live is that you have to basically get a lot done in the first couple of weeks, then the game goes into a bit of obscurity after that," he said.
"We actually had some very favourable reviews of Space Giraffe, and if you look around, most of them aren't bad. It's just most of them came out too late, and by the time the better reviews came out, the game was already off the front page [of Xbox Live]. So it was just a bit spoiled for us, really."
