Thanks for the comment!
If I'm totally honest with you, it never occurred to me to explain the basics like "you want to have more cards your color" or "bigger number flips". I figured people might be tripped up by some of the more complex rules, so I explained those. Not sure what you mean by "supposed deck building" either! I went ahead and added some more text to the game page description, maybe that will help others.
This is a game that I largely made for, well, for me. I've been wanting a way to play Triple Triad, so I made that.
It's okay if you didn't enjoy it. Thank you for giving it a chance.
