It's like Surv Island, but with more plot, and not half as hard on my phone. It does have in-game "billboards" advertising free stuff you can get if you watch an ad, but since I mostly keep my data turned off, this is not an issue for me. Hey devs, great game, but you should add a "turn off all ads and get rewards free" paid option for those who have money to reward you with! Also an entirely optional "reusable bonus item" and/or tip jar, because why not?
