Fun and educational

The puzzles are very fun and interesting. The only complaint is that the whole game is completed very quickly. It would be great to have additional levels or increased complexity added. Great concept, though. And I love the idea of teaching about quantum states through a game.

Amazing game, and great introduction!

There appears to be a mistake on the very last puzzle of the last level. See my question in the Slack channel under #ibm-q-experience for more details

Loved it

Please add more levels and more complex situations so we can have a more in depth look and a higher understanding of the quantum principles.
