I enjoyed playing this, reminded me of some old shooters from the 90s. I liked the responsiveness of the guns and the voice acting :).
I felt like it could do with slightly better feedback using the bomb wand, it wasn't obvious to me that it had worked when I fired it, and the cooldown was long so I couldn't try it multiple times very easily. I also found that when the ghost monsters got you you died very fast. Perhaps could do with a cooldown timer on the player getting hurt so you don't go from 3 hearts to 0 within a second.
Overall great job.
