really cool concept, I think there needs to be a mechanic where you lose the game or lose castle health or something cause if one of my warriors dies and a goblin get through it just dissappears and I didn't get punished at all for not guarding one of the lanes. and does armor just increase health or does it block damage? hard to plan if I don't know how much damage I can block. which i feel like is a huge part in this game choosing the best lane order.
There is actually a loose Mechanic. U might had an Bug, usually when a Warrior is Dead on a Lane the Damage goes on the Castle if its not Defended. Once the Castle Defense drops on Zero or below the Game should End.
I just saw that the gold and the rounds are swapped in the Game Over Panel. But the Game Over should normally happen when you can't defend a lane anymore. I'm sorry you experienced a bug, I'll definitely take a look to see what could be causing it.
Your damage is irrelevant, you just need enough life and, or shield to survive an enemy's attack. Basically you just block an attack and either the hero survives or dies. But thanks for pointing out that it's unclear. I'd like to revise some parts of the UI and the playfield to make things clearer.
