It was really interesting! I have completed the game although I failed for a while and was happy to manage rounds. PS: but I see two unknown screen for the game, so probably there are more rounds that I have not completed.

Later, my son showed me more levels and finished the game. I was just mistaken and stopped before the real end. It was my misunderstanding, so there is no problem with your game. Just one nuance - it would be nice to show messages a little longer because English of my son is bad, and it was hard for him to understand all messages.
