I like this game. I particularly like the night vision mechanic; your implementation of a flashlight is a lot smoother than my own. It’s also very well put together overall.
The one bit of feedback I would give is that it’s harder to avoid spikes than it needs to be, because the player’s position is floating but the spikes are locked to the tile map. It might be less frustrating if the player’s position was locked to tiles, so that a 1 pixel collision with a spike doesn’t happen.
