I didn't mean with engine to switch the computer engine, but the game loop. There is one aspect which is somewhat annoying, namely the need to activate all buffs manually at the beginning of the fight. Granted, not all buffs make sense then, but anything you could activate without losing a turn and not needing taken damage or spent SP would benefit from a shortcut. Also, the reset of the focus to the starting point of the wheel is unnecessary - I want to start other buffs and having to scroll again to the category is just wasting time. Or the prices for food seem a bit out of whack, considering you can buy land or a couple of chicken meat (is there a way to cook that stuff?).
But those are more nitpicks in the grand scheme. Not sure if there is an issue for others in the greater game loop. Writingwise I don't have found issues with it by itself. It seems functional and different characters have different voices. Maybe those people have high standards? Maybe I'm less demanding than others? Don't really know. But for spelling mistakes, it would help if you took the text and copied into a word/gdoc file. Then most issues would be caught beforehand.
In general, I am looking forward to your next releases. Creating so many different areas, so many different enemies, so many different transformations and classes along with their abilities and weave everything together into a whole is beyond me. And likely to those who complain. But just because some have dislikes for certain parts, don't lose sight of the parts that deserve praise!
