Finished the demo. It was really fun and a lot more challenging than I expected. I didn't wipe but the boss fights were not just simply spam attack. The visuals are also nice. The music that was shown was great and I like the town building aspect too.
My only complaint is that a lot of the costumes don't seem to fit the character. Knight looks awesome on all four and Swordmaster suits most of them but others just seem really off. I thought white mage looked terrible on everyone and Black Mage seemed off on the females. The White Mage and Black Mage female costumes try to go for a sexy look that kind of falls flat with the cute designs of the characters I like the Final Fantasy series red mage design but the look here just felt off. It would be a better fit for a Dancer class.
EDIT: Whoa, whoa, whoa. I was looking through the menu system and just discovered you can change the encounter rate. Increase it to high levels if you want to grind or turn random encounters off completely if you want to reach a boss at full HP or reaturn to battle. This is probably all old hat to all of you but it really surprised me. I did not know anything about this game before laying the demo.
