Keiichi Toyama, father of Silent Hill, is working on a new game, but it's not Slitterhead 2

Keiichi Toyama, creator of Silent Hill and founder of Bokeh Game Studio, has confirmed in an interview with Famitsu that he is working on a new project, specifying that it is not Slitterhead 2.
Toyama admits that Slitterhead, which released last year, didn’t reach as wide an audience as he’d hoped, partly due to some confusion about its nature: horror or action game? Despite this, he is satisfied with the work accomplished by his fledgling studio, saying that sales were not the only objective.
For the time being, there are no plans of a sequel to Slitterhead, though he doesn’t rule out going back to it one day. The Bokeh team is currently mobilized on a new game, putting aside its initial ambitions to develop several smaller-scale titles.
