A Quick Review After Trying It Out

I joined because I wanted to play just one match with my friend. First off, the game can only be set for a maximum of 5 minutes, and there's no unlimited mode, so we couldn't determine a winner or loser. (It's possible I just couldn't find it.) Also, I thought you could play cards of the same number but different colors from your hand according to the official rules, but I didn't know how and couldn't play them. I skipped the tutorial, but even after my friend went through it properly without skipping, they also don't know how to improve these two things. If I had to give it a star rating, it would be around 3 stars.
