My train was constantly beset with birds armed with weights, and the engine would frequently catch fire. Occasionally a crazed lunatic of a man threw bombs from the roof.
But that's enough complaining about Southeastern Rail.
Y'know, I wouldn't normally focus on difficulty in a jam game, but everything else - the graphics, the sound, the controls - are just perfect. They don't aim for anything they don't need to be, and as a result, it looks, sounds, and plays really well. My only problem is that it's too easy: run left when the birds are flying in from the left, run right when they're coming from the right. Occasionally chuck a few more lumps of coal on the engine. You will never be hit, and there's no reason not to let the birds go un-exploded.
At 200km, I got bored, and decided to stop the train and bomb the engine, because that's the sort of person I am; and all of a sudden, things got challenging, because I had to be stood on the bomb cart, find an opening in all the one-tonne bird droppings, and aim my bombs correctly. It was hard! And I died.
...Sorry, I'm back to talking about Southeastern Rail, aren't I?
