Chained Echoes has so much to like while also managing to feel unpolished in many other ways. It's genuinely impressive how much one person has created here, with a strong art direction, a solid story, and some great music as well. The battle system is the area that I take the most issue with. The ovedrive / overheat system is cool in theory, but ends up resulting in more micromanagement than necessary, often getting in the way of strategies by requiring random moves to reduce the heat bar. The Sky Armor battles feel even worse, given there are fewer ways to manage the heat bar. On top of this, too many bosses have the ability to act multiple times per turn, creating some scenarios that feel truly unfair. Despite these quirks, I did enjoy Chained Echoes a good bit, but it wasn't as enjoyable as it could have been.
