Test My Language App and Provide Feedback

My team is developing a mini-game to help people learn a new language. All I need is for you to try the game on your Android phone (the game is not available on Apple phones) and tell me how you think we could improve it. We would do a video chat, have you download the game, and then you try it out and tell me what you think I need to do to improve it. The reason for the video chat is because I want to see exactly where you might have struggles with the game. This is a very simple task, so I'm only looking to pay $2/hour (you'll be paid a full hour even if it only takes us 20 minutes to test). But if you are providing very constructive feedback, I will increase that rate.
