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.

I do this but instead of a playlist it’s just Rockefeller street Nightcore version on loop
