All steam-accepted gamepads should work just fine. In-game button prompts are still keyboard demonstrations only, but that will change in the near future. Check Cyber Volley's demo and enjoy!
There is also a new minigame, accessible on the right-end of the hub scenario. The character who gives you access to it is a mole, in a placeholder fashion. Just like the Nyota character's chibi sprites are still being placeheld by Stella's sprites.
For now, I am working on character dialogue, to give the game a non-intrusive narrative aspect.
Please, let me know what other changes/improvements you want to see in the game!
