Hi Raffile, congrats on your submission to the jam! I liked the evil backstory to the game and the music. I think things would be much better with a bit of direction, I was unsure where to go and explored for a bit killing enemies. I found the rooftop of a building but I didn't know if that's where I was meant to be.
I think you did well with the art on top of the pure black screen, it looks super-retro. I'll have to check out this Byond engine as I've never heard of it before!
