I like it

Its good for beginners and teaches simple tactics. There is also things for more advanced players.

Its a great way to learn chess in a way you would never think to do it.

An idea on how to improve: create the idea of a non-tactic. The position can be set up where no tactical gain is available, and in those positions people can choose the non-tactic option rather than trying to solve. This prevents people from just trying the only move that makes some sense without really calculating the position.

Anyways 5/5. I hope this app gets more recognition.
