Not an answer in almost four days(week days) for something which you released yourself less than a month ago is a bit too much.. But anyway, Bewitched 1 was a game with nice characters, a good enough scenari to support them and this awful rpg maker basic battle system.
It was good for it's price range. However, this one Cost 10 Dollars, which is another category entirely where huge load of really good indie game can be found ; That's why i do think that my question is pretty legitimate and as much as i liked your past characters, i won't give ten buck blindly.
My apologies Lytel, I've been taking a short break and haven't been as active lately.
I'd put the length anywhere from 12-20 hours depending on if you're a completionist or not. The highest time I've heard so far is 24 hours from a person who 100% finished the game, but I could see someone rushing through it in 8-10 easily if they wanted to.
On the battle system, Celestial Hearts uses a side-view ATB system (somewhat similar to the older Final Fantasy games, where each character takes their turn immediately after their ATB gauge fills up). It's definitely more engaging than Knight Bewitched' battle system was, but it is still an RPG Maker battle system.
I went ahead and uploaded a demo - you can try the game for free and purchase it later if you like it!
