I was thinking about running this game when i got it shortly after release, i never did get round to getting a run i was happy with but i do know that on the early versions there was a death skip that saves time if you walk into the static area, it was fixed in this patch its the removal of the checkpoint on floor 3 https://store.steampowered.com/news/app/3290710/view/4476110102203466555?l=english

This old of mine run shows that skip, the downside is all the bodys and bottle will block you path like crazy so may not be a time save overall
