Yes, no idea why people think it's something new since it's been the case since 2015. 3rd party clients aren't supported, it means you can get issues while injecting vape into them.
Safewalk just prevents you falling depending of where you're looking at.
It depends of what you want :
100% of youe speed but having 30%+ falling rate or
90% of your speed but having 1%+ falling rate.
No, it's just discontinued, it's just an autoclicker, nothing more. Vape lite & v4 both work on most of 3rd party clients, so no need to keep mantheclicker working. And it wasn't an actual product.
