yeah I am not sure why the buzz saws do that some times. I never noticed that they were doing it from time to time till I was play testing the game a fair amount of times was like why is that there went into unity to fix it and noticed it wasn't going to the wrong spot there so was like hmmm. But I should do that in one spot like you say to force the player to use the ghost mode.
As for the grinding part I forgot to reset the scores when pressing restart I did fix it with the newer version of the game but I guess all the jam players that download the file and don't use the web player version will be able to do that I will probably get rid of the scores that do that later on since that would be on fair for future players. And yeah the deaths were also not reset as well sorry about that.
