level 5: 00:00.17 (this was already good here, but must have been just enough difference when I saved 11 in Level 1, maybe it's a frame rule, not sure)

Time save comes from fighting the glider enemy instead of skipping it. I was surprised that was improvable, as I thought the previous method was the fastest, turned out to be slower then fighting.
