The word "unique" doesn't add anything to this. Everything is unique. Why is it unique?
From the perspective of wanting to know in one line what the game is, I would add minimalist graphics and isometric.
As a YouTuber, if this was in my inbox, "isometric" probably would've made me less interested to be honest. That said, when I actually clicked the link to check it out, it does seem interesting..interesting enough I'd like to give it a shot and maybe make a video of it. I don't see anything about price or downloads? You should at least mention that there isn't a way to get it yet if there isn't.
