Generally great, with a gorgeous art style, fun worldbuilding,  and an excellent soundtrack - and while the controls are fairly awkward and unpolished, the game has more than enough charm to make up for that. 

A larger concern, though, is that it doesn't want to run natively on Windows 10. I have to set it to compatibility mode for Windows 7 to get it to run. I unfortunately have to reduce my rating for that, it's a pretty rough issue to ship a game with.
