Journey of a Roach's strong ideas loses too many of the conventional adventure game's strengths without gaining enough from them to compensate. It can't even retain the strengths of its setting, quickly jettisoning its post-nuclear scene for a standard flavour of cartoon zaniness. Too many basic lessons on how to treat players go unlearnt. Even over its short duration, initially colourful scenarios become sadly static and tired. Journey of a Roach has some promising ideas, but unfortunately struggles to demonstrate them at their best.
