Okay, I don't think I can wait for all the points to add up, not trying to brag but I scored WAY too many points, hah.
That was interesting! It didn't feel as much like a full game, as it did a single mechanic for another game - but, it's a pretty darn interesting one! Would be great for a horror game, or perhaps something stealthy, where you've gotta time releasing the mouse button with the sound of doors closing or thunderclaps.... mmm. there's a lot of potential in this mechanic! I highly encourage you to work this into a full game in the future! :D Good job!!
(Also - in the future - if you need stock photos but don't want to have to put up with watermarks, try some free stock photo sites, like Pexels.com, or Pixabay.com. Pixabay is probably my favourite - don't know what I'd do without it! Still, *any* stock photo is better than an AI image, even if it has a watermark... hah.)
