Is this not on the pico-8 BBS? I'd kind of like to put it with the rest of your games my pico-8 library.
(I'd also kind of like to be able to make edits - Have you considered giving the saws little motion trails so it's easier to tell which way they're going while they're moving slow? Sometimes I think a saw isn't going to get too close and then it slices me in half.)
