A modern programming language that makes developers happier.

kotlinlang

Hi guys! I've just started digging into gamedev, so I'd like to get advice on what should I use. I want to build a very simple (in terms of graphics) Android game, and I would love to use Kotlin since the language is amazing. The game is just a card game, so the most complex animation I'm gonna have is flipping cards. 
As far as I understand, LibGDX (and LibKTX) will be enough for that. Am I right? Are there any noteworthy alternatives to take into account? I have vast experience with serverside Java, so using a pure Java Library in my Kotlin project is not going to be a problem.
