This is the second game of yours that I have played on my channel (first one was Old Friend). I would call it a creepy horror that relies on the anticipation of a jumpscre about to come. I had fun recording it for my video. Your game mechanics are really smooth. One suggestion: see if you can develop a detailed storyline for your upcoming projects. It will make things interesting overall.
I tried to blend the concept of creepy knocks into a funny infomercial about a tablet called Thak Thak Gone (translates to Knock Knock Gone from Hindi). If anyone here is a Hindi speaker, please feel free to check it out.
Thanks!
