Thank you for the feedback, that's really helpful to hear. I went ahead and extended the time before a hint to 14 seconds. I had also been thinking that if you didn't want to be bothered by hints, you could just turn them off under Settings - but maybe that option isn't very obvious.
It's hard to judge these things as someone who's played the game a thousand times, so it's a huge help to hear your thoughts! Thanks for playing and I'm glad you enjoyed it.
