Firstly, I'm sorry it took you so many attempts.

In fact, we made some plans for instruction of the game at the beginning. 

However , we failed to achieve our plan because we joined jam too late. 

The only method we can achieve is to add text to the scene to guide the players. Althrough it is not clear enough.

At last, Thank you very much for experiencing our game, and I'm glad that you finally win.
