- Add an alternative hardcore mode in to the Start Menu, that appears after getting one of two real endings (corrupted and escaped). In this mode you can increase the speed of Whererat a little and give to the player an ability to survive after 2 bites (but third one will be the last) and another ability, to close and open doors while running in search of the key. Closed doors can slow down the Whererat for a little, but also can disorient the player....
