Vampire Survivals (Gift Code) Android Gameplay

At first I was excited to see vamp survivors android version. Pros : - free and no in-game purchases, but I was wondering if they using background ads - should be potato phone friendly, my mid phone can play this game real smooth and my phone doesn't get hot - you can play this offline Cons : - as I write this, controls are meh, and can't move facing backwards - graphics Conclusion : - some of you may not like this game, but when you do, it's the best game for wasting alot time
