Beautiful layout and a clear, simple game design like v5. Htv has numerous moving parts and many subsystems, tons of lore. This new version of htr hits a great sweet spot.

Wonderful seller and awesome product. Only complaint is that the app picks up any bright light (lamps, tv, windows) and creates lines you don't intend.

The pen draws extra lines, very difficult to use. Requires to have two smart devices and they each keep disconnecting from each other. The lag also makes the timer unusable.
