Nice Design, damn that Jump key
I love the look of the game, and the atmosphere but as has already been mentioned the jump key is an absolute nightmare in terms of it's responsiveness.
During the "slower" parts of the game this is just annoying (i.e. having to try to jump several times to get where you want) but on the tractor level it is unbearable. You have a level where speed is of the essence and reaction speed is vital. In and of itself not a problem but you have a jump key that doesn't work half the time - that's a serious issue with the game.
As I said, I love the look and feel though and I'm going to give the second part a go now in the hope that the glitchy controls have improved. I think the game has a lot of potential - nice one.
