Not the person you asked for, but there are two ideas where this can work:
[Devour Them All]: Devour all 30 students (40 students for Nightmare Mode) before they all escape with the same time system. AI’s will actively run away from the player when in sight and hide places where the player must look through. The twist is that the player’s hunger is always low percent (Ex: Max cap is 15%), and running now decreases hunger. After digestion, the player will get a brief boost of speed to catch up with the running students. This is akin to Nightmare Mode.
There are also traps lying around areas that stuns the Apex Player and also some students may carry apples (Ex: Green or Crazy Apple) that can make the situation even worse if the player eats them.
[Hunt Mode]: Same as Devour Them All, except you’ll have to find one student (Which is the target you must eliminate) to devour and win the game. This is similar to the regular game where you play as a prey and the predator only hunts you but mirrored that you’ll have to find them in a crowded university (30 students). The “target” will always try to hide and unlock doors on their own. The only difference is that the Apex Player will always be able to devour, and the “Target” prey will only struggle (And having very high chance of escape).
How the player will detect if the prey is their target is looking at something suspicious about them (Ex: Carrying items, different walking speeds, crouching, hiding in obscure places, etc). Also, student predators can’t be the target, and they can’t devour the target either.
