Really liked the atmosphere and the mystery of it. The world seems very logical and everything has a reason why it is there. The riddles were very nice but at times too hard for me.
For example, as a non-native speaker I don't know what you are referring to with "cultivator". Also, it is not clear to me why some actions can be done with brutal force - pushing a trailer - and some require equipment - unprying the horizontal bar with a jack. I think I spent 15 min to get on the hay bale and cut the rope, because I was struggling with the commands. I also don't see why you would need to get the crumpled note before crawling into the hollow.
There are a lot of rooms which means you will have to do a lot of backtracking if you find something that fits somewhere else. Also if you miss something you need, you have to revisit 30 rooms to find out if there is anything else.
