Ehm... I'm stucked with a bug: I cannot talk with anybody. On the top part of the screen I read the instruction "attack with Steel Sword" and it don't go away.
There's a lack of continuity: at the end of the first round it's frustating to start from the beginning. I would have developed it this way: at the end of the first round, another bigger tower is added to your castle. The archer becomes automatic and the enemies a lot stronger. So you have to increase the power of your wizard, whilst all you made to your archer remains useful. It would be cool if you can choose which enemies should be attacked first by your archer. Would you consider this idea for a sequel? :)
**** for now. :)
Unequip the steel sword in your inventory. You don't need to equip it, it will automatically attack with it when next to enemies.
