Thank you for your videos!! It helped us through quite a few. Did you unlock an achievement when you got 4 stars on all campaign levels?! We just finished 6-6 with all 4 stars and I expected to get something! I don’t think we’ve done kevin levels yet... do you have to get those as well? So much blood sweat and tears went into it. Mostly tears.
Thank you for watching us! We're glad the videos were of help! There are no achievements related to getting 4 stars as far as I know. As for in-game unlocks, the devs do say they've added "a couple of treats for players who complete New Game+" but to be honest I have no idea what those are. :D (maybe a new chef or something?) If you still haven't run out of blood and tears you should definitely do the kevin levels, too. They're lots of fun =)
