I've done the bloody death a few times on the bridge map (in the "very hard maps-download and enjoy"). For me, what happened was I would try and jump straight off the deap-end near the start and sometimes the wolf would catch me slinging me straight down to catch for a 1/2 sec on the floor...
Out of couriosity, has any1 actually beaten house? Been making screenshots as I beat the "harder" maps and so far beaten every map in lugaru except the last standard and this "house."
