3 stars: The game is fun and the concept is sound... The only thing keeping this game down is the app doesn't have a cast feature by itself. Mirroring causes a noticeable lag and it obviously, but very annoyingly, mirrors your left and right making it super difficult to draw anything properly... If you put a direct cast from the app to fix these two minor issues, you'll have the game of the year.
3 stars: I figured out how to eliminate the random lines being drawn simply by using a tripod so the phone does not move or shake. However, the app is an easy 5 stars if it had the ability to mute out the awful music. Gets real annoying quick. I know I can turn off the sound, but then I can't hear the timer and other things. Should be able to mute only the music please. Maybe I'm missing this setting, but don't see the option
5 stars: This app is brilliant in its simplicity. The camera picks up bright green light and superimposes it on the video. That's all. So, of course it's not going to work in front of your Christmas tree, or in front of other bright lights. There has to be enough contrast for the camera to detect the wand. If you take some time to figure out the best camera position and lighting for your environment, you won't have any problems.
3 stars: It is a great game me and my family played it many times. the pen some does not work only if it's in the right position also the tv draws lines without the pen. Please consider a casting option for better casting.
