i think this is turning out pretty well

I made a paper sword

Although it's more of a black knife now

I'm gonna make an entire song for my FNF mod based on this (first image is an idle concept)

3 secret songs have been thought of from this animation

1: wah-ah break-ah (Game breaker but Rewrite Bittax and @Noahthespeedvolt_1997 sing it)

2: bo-le wah-ah (An original song based on this ending with Noah being kicked in the water)

3: (no space left)
