Coming from Playtonic's Gavin Price...
...The aim is, with the amazing support we've had from fans, to now make Yooka-Laylee bigger than Banjo-Kazooie.
Some people were worried that the $15 Kickstarter price and the lower amount of worlds would lead to Yooka-Laylee being a smaller game. Nice to see Playtonic putting those fears to rest! Thanks to Ripa for the heads up!
