The combat feels... off. Either you are curb stomping your enemies with ease and taking damage from nothing, your enemies do no damage except for one-shotting you with a skill (even your tank), or you just get a slog that takes forever to get through. There is little "middle ground" where you and your opponent feel like you are trading blows in a semi-equal terms. It would also do well if basic attacks and single target spells were a little more powerful and possibly gave more TP.
Also the button-mashing level up minigame needs some mixing up- it gets old after a quickly, and there is little customization with your harem's combat abilities. Also, 6 activity points are too small for the size of the harem. Also, a means of getting to the Haremettes quickly would be nice.
