Took a few tries, and some good luck with wave 6, but I believe this is the WR.

It looks to be faster than Kuhy's run by a little more than a second. I didn't have a good timer so I used some frame counting to get the time.

My Run: Play button clicked at Frame 23 of 0:20 (Frame 623), You won screen at Frame 1 of 4:33 (Frame 8191)

Total Run Frames = 7568 4:12.27 Runtime

Kuhy's Run: Play button clicked at Frame 23 of 0:09 (Frame 293), "You Win" screen at frame 13 of 4:23 (Frame 7903).

Total Run Frames = 7610 4:13.67 Runtime
