You are a valliant knight. You must find a steed whose physical charictaristics match your riding style. One you've grown accoustomed to your mount you may find good or bad things about it's temprement. Chocolate is a strength upgrade. Roses are horse feed. Diamonds are horse armour upgrades. Folders are melee upgrades. Skulls are pikemen. Girls are rouge rustlers. That is all.
Loved the first 10 levels, started getting a bit frutrated for the second 10, and absolutely loathed the game by the end of it :p still, have a new badge and some time killed.
