Very difficult :D But after multiple tries you get the hang of the ability system and start getting some awesome combos! (I cannot beat the vampire because I am bad)
I am not able to register anything through my microphone seemingly. That or the game doesn't show that anything is registered. I wish there was a little more clue on what I was doing. Cool idea though.
I thought it was a fun game, not sure how thematic it was. I had to keep switching between fullscreen and windowed so I could scroll to the controls, as I spent 5 minutes in the first room stuck since I didn't know you had to slow time down.
