The strongest aspects to it are just how much it leans into charm and being unique, as well as using that charm as part of the gameplay design. As in, in order to find your way forward you're going to have to talk to everyone you can, which you're encouraged to do because the dialogues are so fun to read. There's a very sweet and emotional side to the game as well, and the ending sequence is an all-timer. Just lovely. Also the suspend/rewind/save state function on the Switch version is a great way to experience it, and allows you to bypass a lot of repetition and headaches.

The less good stuff is in how some enemies are pretty bs, and how certain mechanics required to advance involve a certain amount of lateral thinking in ways that only occur once in the game. So at times it feels like the game is really trying to sell you the official strategy guide. For instance, in the last fight it's only minorly hinted at that in order to beat the final boss you need to use a mechanic that until that point has been more or less useless to you. The game also has way too many items and it's not always clear which ones you're going to want to keep around and which you'll need to use the very clunky storage mechanic for. Undertale for instance, which was HEAVILY inspired by this game, solved that by giving you universal storage often throughout the game.

It's very good and feels like a completely realized vision, which is certainly rare in games.
