I enjoy this game a lot, even with some of the things this game needs to polish such as the FPS issues and some animations that are longer than they should be (witch's ice attack, poison damage having a 4th miniscule wobble that takes up half a second, etc). Grinding this game is fun but sometimes can get tedious for a number of reasons and I have some suggestions to make it more fun:
-Reducing unnecessary parts of animations. This is one of my only big complaints, as pretty much all of the animations are pretty slow(in my opinion) even when sped up, which inflates the amount of time it takes to do anything.
- Speeding up most of the animations. The transitions in the 'visual novel' parts are fine, and most of the basic attacks are a good length(in my opinion)
- Nevermind, the animations being ridiculously slow was caused by a low framerate. For some reason, now it's magically running at 60 FPS. I'm curious what engine you are using. Until you can fix the FPS problems I'd suggest you have the game's time run on real time, not frame time if you can, especially since in a game like this(2d, not much moving around really fast like in a first person shooter), bad FPS doesn't really hurt the experience as much as how much it slows down everything.
-More defined level system with exp to reward more time spent in battle(right now there's no real reason to not run away from all minor battles, you generally have enough money and items)
-Generally more rewards from battle.
-Difficulty scaling depending on the power of your Haremon.
-During a dungeon, the turns should end and the next one should start right after the event is finished.
This game seems heavily inspired by Pokemon, I would suggest you look at some of the animations, game mechanics, etc. of Pokemon and try to make your game flow similarly because Nintendo fine tunes all of those things mentioned perfectly.
