This game ran fine for me, no glitches or lag even as I rose through the waves so far. It’s very simple and easy to get into and stop if need be, and there’s no pesky ads that pop up out of nowhere (so far at least but this is good news to me) there aren’t any offers of in game currency or double damage or fire speed I’m exchange for watching an advertisement but I kinda like that since my play isn’t interrupted by a constant barrage of ads.
This one has potential and I hope any future updates expand of the content, which is the only mild hitching point at the time of writing this.
