Maybe cuz nobody knew, but you can kill the winter lanturn.

It says "Prey Slaughtered" when you kill it, which only happens with the three other major bosses. You also get insight for killing it.

Also the rules says everything has to be on recent patch, but like nothing is. Maybe just make a new catergory at this point? Idk just sayin.

You can do infinite sword glitch on the most recent patch. I know a couple ways of doing it.

A - Hold left attack (unequipped) and then start holding right attack soon after(about halfway through left attack animation) Keep holding both buttons till the animation has fully played out. You may need to go next to something to see the active hitbox.

B - Pressing roll and attack while landing. You might need to roll off the ledge as well. I'm not exactly sure, but this just happens a lot accidently.

You can't seem to stun Father G the same way, maybe because the knives do less damage. The knives are still good for parrying Gilbert tho.

There's my food for thought. This demake is so cool, and really fun to speedrun.
