I did a very small interview with Anders Mårtensson of Illusion Labs about Labyrinth 2. 

How long was Labyrinth 2 in Development? 

From start to first release took about 9 months for 1-5 people. Then we have worked on it on and off for a couple of months, doing updates and fixing bugs.

What is it like developing such games as, Touch Grind, Labyrinth 2, and Sway? 

It's great! I love having a creative job and no boss who really tells me what to do. However, it's also a lot of hard work nailing down those nasty bugs, but once you read all the positive reviews and all the fan mail you know it was worth it! 

What can we expect to see in future updates? 

Not much, L2 was complete from the start and the other games are quite old and it doesn't make much sense in updating them more as we have already done numerous updates with new content.

Are there any future games your willing to "Spill the beans" about? ;) 

Sorry, no ;) We are however working on a new game and hopefully we can tell you about it in a month or so!
