I still think they will release some sort of DLC...eventually.
But speaking of stretch goals, I saw someone in the comments section on the Yooka-Laylee Kickstarter page say that Grant Kirkhope apparently confirmed there was no longer going to be an orchestral soundtrack (which I'm not surprised about, as recording that would be so expensive, and I reckon they needed that money to help them fund all the extra effort required to get the Switch version of the game up and running). I'm happy with the music in the game as is, but I'm sure some people might be disappointed about that.
Excellent news! Good to hear confirmation they're still working on Yooka Laylee DLC as well as what I can only assume might be a new project. I'll be looking forwards to when they start talking more about them.
Didn't most people bitch and moan about the idea of Y-L having an orchestral soundtrack? I remember Grant being really excited about it and then being shocked by the negative reaction. Doesn't seem like Playtonic can win no matter what they do.
