English Grammar Test Game

I wish this app could be much longer than this, I wish to continue to creating higher levels.

Developing speaking the app is very good, is intuitive and easy to use. About English grammar, I was looking to test my grammar usage, so knowing the name of a comma it isn’t what I was looking for. It has many questions about what is correctly written (but as you can see my grammar is quite messy) and I am trying to test this. Probably developers might divide the app in two: usage and rules, and make it a little harder to pass levels, and add more levels.

I went through (3) levels and some answers are incorrect (plain as day). I even checked on google to confirm. Would be a great, educational app if all answers were correct. I would’ve also liked to see, after answer selection, a little blurb of why the correct answer is the correct answer. Thanks!
