Accidental new discovery in -1, topped it off with a decent 8-4 as well.

Timer in -1 counts down by 2 frames instead of 1 hence the time save. Same thing happens in -2 normally.

Timed on emulator, I don't recall the frame numbers for entering the final room though.

Grabbed the ax at 13502, minus 218 for starting frame = 221.0359 = 3:41.036.

Played on everdrive n8.
