I bought a bluetooth keyboard for my tablet and was surprised to find that the mobile app didn’t have full keyboard support. The arrow keys move the player but that’s about all I found.
I have the Nvidia Shield tablet which has a dedicated controller. The app seems to have full controller support, which is why I’m hoping keyboard support could be added as well.
EDIT: Plugged in a mouse. Doesn’t appear to have mouse support either.
I’m not ruling it out completely, but it’s unlikely we’ll add this any time soon. There just aren’t enough people asking for this feature for us to commit to it.
