I also bought it and completed it over the weekend - about 3 hours I reckon. Certainly laugh-out-loud funny in a few places. Nicely surreal and funny, and very well animated.
It suggests it's better with a controller, but I played it just with the keyboard, and it was totally fine.
Not sure how well the humour will travel (it's set in a fictional Yorkshire town, I have mostly lived and worked in Yorkshire) - though I'd imagine it travels fine, because Yorkshire humour is obviously best :)
