Let's take a look inside an ant's nest. You're sure to be comforted by the sight of these little creatures trying their best to live. You can not only watch but also play pranks on the ants. Bomb:You can make the place you tap explode.The ants are so startled that they are unable to move for a while. Spider:You can spawn a spider wherever you tap.Be careful not to let too many spiders appear, as they will eat ants. You can also help ants become more active. Potion:Potions have been added as a new item.You can use it to nourish your ants and speed them up. Once the nest is full, a new queen will emerge and you be able to start a new nest. Let's fill the screen with an ant nest. Please watch over their daily lives. [Notice] This app is a remake of its predecessor app "Ant City", using the new framework Flutter. The basic game content will be the same as Ant City, but we plan to expand the levels and add new contents.

Verdict
The clearest difference is in-app purchases: RE at none against RobotVSAlien's 1. RobotVSAlien's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.
