Thanks for playing and glad you enjoyed some aspects, i completely agree about the tree cutting - there is no reason to make the user wait lack of play testing, the train part i am not sure I agree with as it also keeps up with the track building, glad I didn't release my first version where it moved half the speed to start.
Regarding making this a longer game... originally I wanted to but now want to focus on next Chapters maybe can get back and expand a little
