It's a solid concept for a puzzler, though the last mission threw me. I managed to clear it, but it was more a 'try shoving the crate everywhere' kind of clear than a 'aha, I know how to solve this' moment. So many enemies all in the same cramped space makes their cycles hard to grok, especially when you also have to factor the crate into it. The 'skip turn' mechanic also wasn't that useful, to be honest. There was one time I definitely had to use it, but all the others I 'saved it in case I need it' and wound up... not actually needing it.
Art style's great though, and I love how the levels rise/fall and assemble themselves.
Character's idle animation is a little odd; it kind of looks like her hat is breathing whilst the rest of her stays stock-still.
