I noticed that when you play in english, you get voice overs when you collect a power up, or when speed goes up. I switched to german, wanted to see if the translation is any good, and then noticed that the voices are gone. Is this intended? Will it get voices in different languages in the future and these are not implemented yet? Or is this just a bug?...

Mark my words, this is going to top the charts. Just you wait

^^

Can I play the game with an Xbox One gamepad or is the feature not implemented yet ?

I/We hope so...? :)
