Good way to spend an hour! The radio is amazing, all of the music is the right vibe, and the DJ reminding you about hydration/discord isn't intrusive enough to get irritating (plus, you can turn it off, which I didn't want to- the DJ has a very nice voice.)
At the moment, I'm looking forward to seeing how the full game keeps things interesting- playing for 30 minutes was very engaging, but right now, I can't see myself coming back for multiple play sessions or getting really invested.
Great game!
