First off, I need to say the lasers are too fast. They're excellently telegraphed, with unique audio and visual effects, and the lighting/bloom on them contrasts greatly against the dimly lit interior, but there simply isn't enough time to accurately react and find a safe spot when playing as intended.
That being said, you nailed a creepy aesthetic and atmosphere, and the pixel art on both the player character and the creatures is really appealing. When the spawners were introduced to the creatures I needed to eliminate, the game became quite tense.
Overall good work!
