Obulis review. Classic Game Room presents a CGR Undertow review of Obulis for PC developed by IonFX Studios and published by Meridian4. Obulis, having made a name for itself on smartphone platforms, comes to the PC with over 150 puzzles and high-res visual design. By cutting the chains suspending a number of colored balls, you can manipulate their behavior to get them into the matching targets. The only rules are the laws of physics. You'll gain an appreciation for momentum, velocity, impact direction, and the behavior of pendula. This video review features video gameplay footage of Obulis for PC and audio commentary from Classic Game Room's TJ.
