Please assess my Android game for those who learn English

Hello everyone,

I have developed a mobile game, with my many years native speaker English teacher, which is intended to test and improve English grammar knowledge for those who actively learn English:

It is available for free by the following link:
https://play.google.com/store/apps/deta ... game&hl=en



Could you please install it on your Android device and play at least a bit and point me out what could be probably wrong with this game? Why isn't it popular among those who learn English? What should be improved?

Thank you very much in advance.

It's a nice game itself, but does it only teach parts of speech? Learning the difference between nouns and verbs is fine, but there should be more to it than that.

The re-odering letters puzzle needs some sort of hint.

The collision box for your spaceship is a little too big.

I love it. Thanks for your developing the mobile game
