We just released a new development version of our game.
Issues found by the community were fixed, audience calculation got improved. Our sources (available at GitHub) got revamped in many parts to incorporate our new framework "Dig" (also available at GitHub).
Gameplay of TVTower never felt smoother - check it out now and download (Linux, Mac, Windows) it for free (no costs, open source!).
