Can only grapple onto certain blocks. Fire & Release should be 1 button, not 2. Have Click +Hold to fire, Release to let go. If there's climbing the line, make that automatic while holding LMB, or do RMB to ascend.

Let us know if you have any questions, or ideas for more content in future for free DLC/updates.

Hope to hear more about the project! @dev
