i have a few suggestions to make it more aesthetically pleasing.
1. edit Fun Bot's idle screen to say "Psychopathy.exe Successfully Loaded" to make it seem like he's got a virus in him.
2. make Gray alive, but just terrified out of their wits.
3. make the dark blue guy with the hood (idk his name)'s idle animation just a subtle smile, and keep his singing sprites to their original.
4. give the white one (ALSO DONT KNOW THEIR NAME) a bloody knife. why not?
that's really all from me.
