Anuto: Another Ugly Tower Defense

Sorry... No, I didn't make it! I found it on the list of recommended apps for DivestOS Mobile: https://divestos.org/pages/recommended_apps

The engine seems custom: https://github.com/mjaun/android-anuto/tree/main/app/src/mai... but don't take my word for it :)

Great game, but be warned, it's very addictive!
