Hug Me While The World Collapses

Respect the theme, i understood the turn-base aspect of it, but the battle royal didn't make sense to me.
The graphics were simple.

I'm sorry, but I just can't figure out what's going on at all. There's a sink coming and the controls don't seems to make much sense for me.

I liked the cardboard cut-out look of the game but I had a hard time understanding how the controls worked. There isn't a clear indication of what direction you chose or what the goal was. All I gathered was that tiles were sinking, and you needed to set a direction and press the action button to move?
