Not long ago, the Bad North game got a good amount of attention on Steam. This minimalist roguelike strategy that was also a hybrid of tower defense and a puzzle game is pretty popular even today and now, it's Android version is up for pre-registration.
In this case, you'll again be able to defend your grid-divided island against Viking invasions. The mobile version will feature the same gameplay and distinctive (and really nice) graphics, as well as plenty of strategy/puzzle challenges.
All of this seems like a good option for an Android title, so anyone who is into games like this and titles similar to Into the Breach should check it out. Right now, the easiest way to do that is to pre-order the title on its Google Play page.
