Replay Glitch on Lil Slugger and CHAD

WARNING ! A LOUD sound glitch may occur after beating Lil Slugger (or any possible boss). Turn the ingame music off or press M on your keyboard ("?" key for AZERTY keyboards) to cancel it.

I took it from Vorpal's video, huge thanks to him for his explanations

Go on Forest
save a replay on 1-16x
exit to main menu
watch the replay
exit the replay with backspace on your keyboard, the game will send you in the level selection
Go to Lil Slugger, then the weird thing happens
To play a level, exit to main menu or the game will send you to the replay when you enter a level.
On Hospital, repeat the process (You can use the same replay. You don't have to replay 1-16x to repeat that glitch)
If you do the same on Brownie, the game crashes.
I didn't try the other bosses yet but apparently it also works with Fetus.
