I basically complete my tower defence game and I was wondering what is the best way to balance it. I have three different groups of towers and three different groups of enemies which all have 4 types in each group. So my question is what’s the best / most logical method of creating a balance game so wave 6 isn’t too power compared to wave 10 and a upgrade for a towers isn’t too powerful.
Any suggestion would be great as I have a few ideas for creating a indexes e.g. (100 damage = 3.4 gold) then I can use this to set the upgrade costs.
