Supaplex: Original Levels: Level 93: Timing!

This level SUCKS!!!! Damn gravity part!!!!!!!!!!!!!!

Does anyone resolved this level in NORMAL SPEED, i mean in the original
speed of SUPAPLEX, not MEGAPLEX nor SPFIX63.EXE Program? It's the
hardest level and with slowing speed it can be done, but in normal
speed, it's almost impossible...
