It's been over a year since the PC client received any love.
I've been hard at work with updates and changes, ultimately deciding to focus on the mobile version first which has received over a dozen updates from the last year. All of these updates have now been applied to the Steam client.
Keep in mind this is basically a straight mobile port, so the UI and UX probably won't feel the greatest yet, but this update allows PC players the chance to test right along side the mobile version.
Enjoy!
