Hey, here are my thoughts on your game:
I like that it's spooky without being too scary, like I'm not so freaked out that I couldn't play, but I was still nervous about being chased in the dark. You achieved a good balance there.
I think you really need to integrate the instructions and controls into the game itself, since there's a lot going on (moving, sprinting, jumping, grabbing, the proximity bar) and it's a bit overwhelming all at once. It'd be nice to give players space or time to experiment with the controls and learn them without the necromancer around, like a safe zone or a tutorial level.
I was a bit surprised that shining my light on the necromancer didn't scare him away, since the map layout is pretty tight (lots of fences and buildings) it can be difficult to have space to run away. If the light scared him off then players would feel like they have a bit more control in this situation rather than being at the mercy of the game.
Lastly, I think the sparkling flowers might be a bit too obvious, especially considering that they seemed to always appear in the same spots. You could make them less bright and have several spawn locations to give players more of a challenge.
That's it from me, well done making this in such a short amount of time!
