Hi, thanks for the feedback. We've didn't know the foreground elements were such a big issue for some players, we'll try to reduce them. Thanks for pointing out the knife teleporting bug, I'll see if I can fix it.
As for taking damage during dashes I'm not quite sure what you are talking about. You don't have invincibility after the dash, maybe that's what's tripping you up. You could maybe try playing on a lower difficulty?
Again thanks for the feedback.
