Thanks for playing! In the game, you can die three ways: By losing all HP, by killing an enemy while they have any empty cells in them, and by exploding with the enemy when their countdown hits zero. It's important to note, that when you take parts from the enemy, that give HP, they are losing HP. If they are on a low HP, they might die, and because you just took a part, enemy now has empty cells in them. For example: Enemy HP: 5 and there is a Max HP Module in them, that gives 5 Max HP. You take Max HP module, and now they are on 0 HP. They died while having empty cells in them, so they explode with you.
