Shell hunter？

This is a 3D action-adventure game in which players take on the dual roles of hunter and prey. As a hermit crab, the player must collect key items— “bottle caps”—to earn enough points to win. More importantly, the player must continuously switch the “shells” they hide in to escape the relentless pursuit of an octopus’s tentacles. The game was developed for the 58th Ludum Dare Game Jam and ultimately achieved an excellent overall ranking of 33rd place.
