Thanks very much indeed!
I'm glad you like the contrast in atmosphere. It really shouldn't work but does! I think it reflects my own slightly morbid sense of humour, too :D
I'll look into the change direction/jump issue, but I don't think there's a delay of any kind, beyond perhaps the actual exact same-frame, if you see what I mean. As I've said elsewhere, I wonder if it's more about the jump happening on the key-up rather than key-down (or mouse-up/down) that makes it feel delayed?
Thanks for playing and for your great feedback!
