The health is related to the empty spaces in the cell. As explained on the game page, when the empty spaces go below 80, the cell collapses and it’s a game over state. Also if the x:12, y: 12 position is covered it’s a game over. And yeah, there are bugs because I didn’t have as much time as I wanted, but at least I wanted to show the concept. After all it’s a short jam. Thanks for trying it!
