I really appreciate the personality that you have given to this game both in the overall art style and the characters themselves. It really helps with immersion.
Thanks for addressing the straight issue. I was a bit baffled when twice the opponents had good hands and I won with a measley pair. I really like the art style and theme. Great job!
I don't know anything about search optimisation but I thought to mention that if you search for 'error 143' with a space on the google play store, your game doesn't appear. It works fine with the correct spelling 'error143' without the space though so it is more of a user error problem.
