the control scheme is pretty unintuitive. it took me a while to realize what "combo the jumps" meant
this is further complicated by the fact that only the third jump has any useful height, so if you reach the ledge too soon you restart with the next series of jumps with minimum height and fail the jump.
the camera never seemed to work properly. i have no idea what's wrong with it but it's clearly not following my mouse, it kind of seems to have a life of its own
