Is it morally right to ingest living things as part of a game

The ways humans amuse themselves with games are many and varied.
Is it possible that one day humans will take into their bodies, living things that will aid in the progress  of the game, or even be instrumental in achieving the game's goal - and dictate the winner.

This might seem an outrageous idea.
But, today this new game was highlighted on Twitter.... and so ingestion of some living thing to assist in a game seems a step closer to becoming reality.

In such a situation the characteristics of the living thing might be a game changer for the player - be it that the ingested organism helps provide a boost in energy, or assists in some skill needed for the task, or perhaps its death indicates that the player has failed and the game is lost!
