It's an interesting take on survival and does it's best to create a new experience, but it's fairly boring after a while. For some unknown and odd reason, it reminds me of Parasite Eve, But that's just me.
The battle system itself is without flaws. You gain, but with a price, so it's always on fair grounds. The teamwork system, constantly switching between teammates, is a great idea, but it felt tedious. Always watching your allies stats made me feel like some old announcer guy who sits there clicking buttons and playing God. I don't know what it is, and I don't know why I don't like it, but I'm giving this a 3/5. It's not flawed in any way, but it just felt "wrong."
