Then why bring it to pc? Key and mouse not supported! "FACEPALM"!

On the level where you play as the Nun (Sor Flor?) and hunt the Bride, as soon as I kill the Bride, the Nun drops her shotgun and the game does nothing. It's not frozen per say/the game isn't crashing but during that time I cannot do anything (move, pause the game, etc). Please advise how to fix this. I've tried replaying the level 4 times so far and it always glitches after killing the Bride. I'm not able to get all achievements in the game with this issue present....

Desde hoy voy a empezar a creer en Dios, los de mhyv haciendo videojuegos, con dos neuronas no da para mucho
