The polishing is really good, the visuals and everything, and the gameplay is really smooth and satisfying, this is the best part. But I think the music stopped (didn't loop?) after some time. But imo the balancing of the gameplay is a bit rough, there's a lot to manage (your health, your aim, your ammos, your timings, the scanning [while moving], your position [dashing around to avoid zombies], and protecting and evacuating the survivors / killing them if shapeshifter). so it's kinda overwhelming. I find that mostly my successful evacuations are the lucky survivors from the beginning of the wave when there are no zombies. Great game!
