Is it worth paying 10 EUR for its novelty and creativity, even if you don't like JRPGs all that much?
It's not really a standard jRPG so much as a game where you resolve random encounters with turn-based dialogue and dodge their attacks in (manageable) bullet hell sections. It has different endings based on whether you're violent or completely peaceful, lots of references to games like Earthbound/Final Fantasy 6, great
music, and plenty of charm.
overrated if you ask me—which I know you weren't, but still—and there are some little annoyances like the game crashing on purpose at certain points toward the end and a slow-ish beginning, but it's still absolutely worth 10 dollars if you have any love for the older console games that clearly inspired it (mostly Earthbound). The amount of work and detail that clearly went into it is staggering.
