As far as Unity is concerned it doesn't seem there is a way to export for Roku. "Unity Games" needs to do that and publish it themselves. That is my understanding at least.
viewtopic.php?p=450097 http://forum.unity3d.com/threads/roku-3-port.224729/I don't want to buy Galaga just to try it, but can't you move and fire at the same time in that game? From what I saw you can, but I don't know if that supports the bluetooth remote that comes shipped with Roku 3. Or they could be using the accelerometor (Which is actually my prefered method anyway, as that is what I use on Android). I'm just talking out loud to get a grasp on if it is truly the remote or if a firmware upgrade to the Roku device could fix it.
Dev42, I am with you. I have been considering ways to make my game playable with only tapping buttons and not holding them, although it wouldn't hardly be a scrolling shooter anymore and would move in to some sort of other genre. Regardless it could still be fun.
Just in case anyone wants to see the game I wanted to port, this is it.
