It's only available to select backers from the original Kickstarter campaign, but if you qualify you'll be able to see how Yooka-Laylee's engine and animations are coming along this weekend.
Playtonic Games has pushed out what they're calling the Toybox. It's basically a sandbox prototype of the game that will give backers an understanding of the animations, physics and mechanics underpinning the crowdfunded platformer.
The idea is to give everyone a taste of gameplay without spoiling the opening levels or the end look of the game, according to the FAQ. It's available to everyone who backed from the £20 tier and up, while those who spent £35 and more can get two codes.
To get a code -- if you backed at the requisite level -- you'll need to enter your Kickstarter e-mail address here. Codes will go out over the next 24 hours, and you can redeem the code through Steam by clicking on the Add A Game/Activate a Product on Steam option in the bottom left of the main Steam window:
It looks pretty smooth so far. And the whole Toybox thing reminds me of the small sandbox created for Next Car Game. Hopefully Yooka-Laylee doesn't spend quite as long in development.
