For the first one yeah, backfliping doesn’t let you wall climb. I hope it gets removed and is not a feature. For the second point, the check points are kind of wank (no offence crane) and I thing his working on it but I’m not sure
then again it seems crane has also spent countless hours coding Val to turn in whatever direction necessary whenever the player decides to make a left turn in the middle of a right dash, so I'm sure this will be addressed in the future
