KRUNCH review. Shop CGR shirts & mugs! Classic Game Room presents a CGR Undertow video review of KRUNCH for PC, developed and published by Legrudge & Rugged. KRUNCH - yes, the all-caps are required - is nothing but water levels. I'm warning you right now. Fortunately, all you have to worry about are... well, monsters, moving walls, spikes, electric hazards, bombs, bigger monsters, ghosts, and the ever-advancing back wall threatening to trap you and... well, there's a reason that "KRUNCH" is in all-caps. You're going to be hearing it. A lot. This video review features video gameplay footage of KRUNCH for PC and audio commentary from Classic Game Room's TJ.
