nah, thats understandable, they be obscure af compare to sonicbitchexe.

But for context to each basically:
the knuckles one: is a strange edition of sonic 3d blast with a knuckles that has fingers for hands. Bit of a acid trip vibe

Algo mas: A pasta about the narrator meeting and befriending a fella online to make a fan game. But as the development goes on, the narrators went downward spiral, ending with the creation of the fangame where this sonic transforms to this thing.

And finally sonic 3 hacked cartridge: a hackrom that has a strange story with a victim sally(same as the sonic character) suffering a terrible fate by their killer. As the narrator is then harassed and stalked by the killer to give back the hackrom.
