It takes too long for him to recover. I also got over 2400 pain points and the extra filler didnt' unlock. Glitchy. What temperature and pressure scale are you basing this on? A person can be in pain before they reach a crush point but you don't model that.
I played this and faved it before it got badges. I'd been hoping it would get them. The Impossible badge CAN be done but it requires practice and luck. IF you are lucky enough to get a bunch of well timed white cubes you can do it easily.
137950 Points, starting on lvl 1 and reaching lvl 19. It's not easy, and it's not required, but I'm sure that if you're good it's possible to beat the entire game from start to finish.
