Thank you for your feedback! I will make sure these problems get fixed. I've started playing again recently and got some feedback from others too! It's safe to say, it's not only you but it's also a general problem. I will fix the grass footsteps since they are too loud from what I've heard and read. I think the light seems about alright, even with the lowest brightness, I see quite good.
The game has an announcement at the beginning that tells the player what to do, if you don't get it, look at the desk, there should be an easy guide on how to play the game.
Thanks again for your feedback, it helps the game very much!
