mindustry is free on Android, it’s a tower defense/factory building game (it’s also open source)

I got bloons td 6 for like 7 bucks, for some reason it also has microtransactions but they are not required or pushed onto you. I think btd6 is the best tower defense game, it just has so much content and is still getting regular updates.

me when the final boss is literally unkillable sometimes and many things are now tied to fps (so if you have 200 fps loader will move like 3 times faster)
