A lesson to be leartn about balancing
There is an underlying problem with this game (i'm playing it as I type this). I am enjoying it so far and it's fulfilling it's purpose of making me less bored however:
A squire costs 30 mana, a knight costs 100. The knight should be at least 3 times better then the squire otherwise there's no point in it. As a result I'm simply beating the game with wave upon wave of squires.
If a unit has 100hp and is worth 100 gold then a unit with 300 hp should be worth 300 gold.
