After leaving Sonic Team in 2006, Naka-san created the independent development studio Prope. Because of the wonderful titles he helped to create in the past I am extremely excited about Prope's first game, Let's Tap. Please enjoy this lovely new Let's Tap trailer and this link to a 2001 Planet GameCube interview with Yuji Naka.
Also, I must mention that the lesser known participants in the creation of Sonic the Hedgehog, Naoto Ćshima and Hirokazu Yasuhara, are awesome.
It looks great, but I still have no idea how the controls are supposed to work.
