Personally, I think the AI in Slendytubbies should get a massive overhaul. They just act so stupid; like why does Dipsy run around the map instead of jumping down in Secret Center. I believe they should outsmart you or something to boost up the fear factor.
The ai would probably need a whole rewrite or rework if you want all of that
probably because dipsy knows if he jumps down from the upper surfaces in secret center he could break a bone or something.
"Then why can the player do it????" Probably to give us some advantage or maybe they plan to make the physics more accurate and make fall damage more prominent than in slendytubbies 3
