And no, it is definitely not to late for that kind of feedback!! You just finished version 1.0!

So I'd have to play it first with the mates of mine. But seriously do make a questionnaire! I am a teacher and we practice evidence informed teaching. You need to have feedback from colleagues and users(/pupils in my case) alike! Brainstorm with mates on it! It'll give you very valuable insights!
