As of 0.8.2, Kerfur seems to have become a lot more wiggly, doesn't seem like he can control himself any better than me. Regular 360s, mad drift and etc. He genuinelly can't repair a single satellite, keeps on slipping out the holes in railings. My best suggestion is just reverting the change making him so unstable.

kerfur is unstable cuz ur speeding time by sleeping. fix it by turning him off and on

Kerfur does suck no matter when you're sleeping or not, which is kinda funny but I can see the frustration because it does cost 500 creds which is a lot early game, so I do agree he does suck, which sucks because I love the funny robot.

Kerfur intentionally has some jank, but it definitely isn't meant to be this bad.

i honestly think its kinda funny the game has bad purchases you can make like kerfur, just retain the past life knowledge of how useless it is for you next runs

Yeah, Kerfus performance is very bad rn, it did not get stuck as much in earlier versions imho
