I've seen a couple of people already say it so I'm going to be brief here but the game is rather grindy everything is fine until get to be about LV30 then things slow way down since your too strong for all the previous areas but not strong enough for the wolfs den and honestly I've always felt that the enemies at the beach gave too little EXP for the trouble of taking them down. So to sum it up boost the amount of EXP they offer or add a new area between the beach and the wolfs den.
On a different note I haven't seen anyone suggest new usable characters so I would like to suggest a dragon girl for our roster.
