Oh, it's actually more like a puzzle that we designed on our own... Just that I thought it looked like a chess game. Maybe call it the Jellyfish game. It's not too much like a traditional chess game, instead it's simply about avoiding collision with the jellyfishes and get to the flag. More like a puzzle in general. Apologies for the confusion.
Many thanks for the text speed suggestion! I figured it was too slow too. I'll speed it up later this day
