Ranged and minions are super powerful. Enemies always attack the nearest target, so if the enemies kill a minion, that's 5-7 hp your party didn't take.
Vampire's blood drain is just so much better than paladin's block move. Often with the vampire it's better to fight because you turn a profit in health, which the paladin just can't match.
Mana cost reduction + mana regen + meat mace means you can convert mana to food at better than a 1:1 ratio! Max out your mana regen because even if you don't use maces you can just convert it into more units.
You created every level with an XML EDITOR?!?!? Seriously!? Wow man people go around saying they spent 1,000 hours in MS Paint but you're totally serious!
Also, the game's hit detection apparently doesn't work for projectiles that go off the screen. If I throw my shuriken at a number and turn away, it goes straight through them and ends up on the ground on the other side...
Interesting game, but it's disappointing that the goal isn't actually to get the target sum. Even if you get the target number it won't let you pass unless you've killed all the enemy numbers.
The enigma machine puzzle confused me at first. I thought it worked like a real engima machine so I wanted to reset it when I made a typo, but then I realized it was just a simple cipher.
