Great game! I got jump scared a few times. I wish there was more ambiance and music and a visual indicator that one died and not just the window popping up. The player character controlled a little too sluggish for my taste. I also wish there were more landmarks in order to memorize the locations / enemies placements a bit better. Couple menu glitches. Game like these with the light pulse mechanic are unique and interesting. Overall, terrific job!
Edit: I played up to middle of level 2.
