Cool concept, but unfortunately, my resolution was too low and all I had to figure out how to scan it was the slightly darker single line of pixels at the edge of my screen. You might want to adjust the settings of the project so it keeps aspect ratio as well as fill screen. The font is also inconsistent, since pixel art games should usually use pixel font. Even though it took a while to get the timing down for the boxes in a row, it was decently satisfying. You should also add download instructions so people know how to open .rar files by downloading winRAR or 7-zip and opening the .rar file with it. I liked the ambience and the audio feedback, and I think you should capitalize on those to create a better experience.
