pretty nice game so far.
The battles are indeed a bit easy. But that's ok from my point of view. Better it's a bit too easy, than too hard.
There isn't much of girl action so war, but I'm sure you will increase the amount of that in the future.
ok, things i would recommend:
- show the same information about the save slots as you do when loading a game. first a slot is selected (by an option in the textbox). Stats of the save slot is displayed. Then the player can confirm or chose another slot.
- add a [cancel]-option when changing the girls. Once chosen there is no way to get out of this menu without actually changing something. (like "never mind ...")
-[1] reducing the amount of enemies in the dungeon. since there is no challenge in the battles it gets annoying.
- [2] stop the approach of the enemies if the level of the player is high enough (like: they are scared by the player and won't attack anymore) (either [1] or [2])
- maybe a interactive help (not absolutely necessary). Since you have a pretty linear story (at least that's what i guess) you could add some helping little creature (maybe on the first flour. After defeating it, it helps the player) that gives little hints what to do next. It took me a while till i talked to the red-haired student to continue the story (instead i was searching for the next dungeon level).
But never the less. A great game. I didn't discover any bugs so far. Keep going, looking forward your updates / progress.
