The game is good, if not for a couple of buts. I'll start with the positives: 1. Lots of weapons and well-implemented shooting. 2. NPCs behave realistically, but sometimes they're slow. Now for the downsides: the game isn't supported on 64-bit phones. 2. There are very few of us on the map, It's kind of boring to play when there aren't enough NPCs. 3. The game is only available in one language, I hope you'll add more. 4. The police don't show up on the mobile version, but I'd like them to.
Good luck with developing this game!
