OpenClaw is a multiplatform C++ reimplementation of original
Captain Claw published by Monolith Productions in 1997 about the
anthropomorphic pirate cat Captain Nathaniel Joseph Claw,
who sets on a quest to find an ancient amulet while fighting
enemies and solving puzzles. For this reimplementation
the whole codebase was written from scratch.
