Bit late to the party on this as I only just started playing the demo this evening. I only have two questions so far,
1) I'm not expected to fight every enemy in the open areas am I? That seems way too much. I ended up galloping past most of them.
2) What am I allowed to sell at the shops? I'm too scared to sell anything at the moment incase I need it later.
1. No and with the horse if you bash into the enemies you will get exp. Do not that you have to be in a battle to level up for some reason.
2. You don't really need to sell anything. I just hoarded everything and was raking in the cash plus Eleven, Jade and Erik have a pep power that allows them to double your earnings and exp in battles.
