I got this app to use it on my Apple Watch and loved it. I downloaded the new watchOS 5 and now i can’t use it. Please fix that. Other than that, it’s a simple app but I like it. It is possible to win against the hard level, but I’ve only done that once or twice.

Hard is not possible

The game is really fun and a fun game to play on your watch when you bored and want to play a quick game but I wish the hard version was possible to win every time I play it’s a draw I wish I were possible to win on hard
