Mac OS X: Postponed for a future release due to a game-breaking bug in our programming software. We're deeply sorry, but it is completely out of our hands! We will have to wait for a bug fix patch for our software before we can release the game on Mac OS X. Other than the game-breaking bug, the game runs great on the OS, so we're keeping this as a planned port.
Ubuntu (Linux): It runs without any issues. Be excited, since this port wasn't originally planned!
Android: The game runs quite well, especially on the NVIDIA Shield (yes it supports the Shield's controller). However, we HIGHLY recommend a 5 inch screen or greater for this port! Even 5 inches is pushing it.
OUYA: We are dropping this port completely. The OUYA simply doesn't run our game very well. Why Android PHONES can run the game better than an Android CONSOLE? We may never know.
We plan on releasing the update and new ports soon. We will keep you updated!
