I really like the look of your game.
Castles are the perfect place to start a family, for rats. The king has hired you to travel the kingdom's castles, forts, and keeps and rid them of the rat infestation before diseases spread.
Use the tools of your trade to remove the rats, break their nests, and keep away from the highborns lest you be punished for being in their sight.
ESDF to move
R to use primary action (open doors, look, pick up trap)
Z to use abilities (release ratter, drop trap)
(1 or 2 number key to use ability)
