Played it a couple days, i'm currently in floor 4 of Abyssal Forest. Here are my thoughts so far:
Pros:
+Nice mechanics
+Graphics (drawings and UI) are awesome
+Battles are entertaining
+Dynamic gameplay
+Not difficult, not easy. Balanced overall (which is good)
Cons:
-Mapping is bad. The maps have lots of mistakes but besides that, it feels pretty empty and... i don't know how to say it. It's just bad, could be a lot better since you made use of Celianna tilesets. It's a dungeon crawler, yes, but still.
-Everything is too damn expensive. To earn decent money you have to grind like a psycho, but that doesn't cares because items, armours and weapons have HIGH costs... you either buy general items (potions, mp replenisher, keys or campkits) or you buy equipment.
-This is more personal. I don't like that "random party" system... at all. It would be way better if we, players, could configure our party, that would be more dynamic. You can't let important things like that be decided by luck... for example, i made a mistake and lost the tank of my team (i don't remember his name now but i think it was a blonde guy)... i paid 500C (or whatever the currency is named. I don't remember it now) which is a lot, btw, to get a new member... what i get? another mage, Sordis. The party is not balanced right now... i have Felicia which deals cool damage, i have Tyrund which deals nice damage too (none of them have resistances), Pastelle (which is the healer and that's cool) aaaand Sordis.
If i had to rate this... hmmm... 6/10. A nice game overall, i enjoy it, but it has it's flaws.
Note: this is what i'm talking about:
