Thanks for the comment. Adjusting the difficulty has been a headache, on one hand, we wanted it to be challenging, but at the same time, we didn't want it to stress players out.
No worries, a good rule of thumb is to play the game yourself (if there are no play-testers) and if you find the game a bit boring or easy it'll be the perfect difficulty for the player, the game should not be challenging to the dev.
