Yeah, don't underestimate the Supra- series of games. I thought Supraland looked childish, but then I started playing it and couldn't stop. It's SO fun.
The jokes are hit and miss, but the interconnected world, steady progression and cool mechanics make it stand out. And you can freely draw on the map to mark points of interest!
There are currently 3 games out in the series, with 4th (Supraworld) being in the works.
Are there any keyboards on f-droid that offer word prediction?
I always go back to SwiftKey (but didn't update if since they announced AI stuff) because nothing comes close, but I would gladly change it to something FOSS.
