Very solid game, quite an interesting concept and I loved playing with the oscillator, reminded me of high school. The voice acting was also a nice touch. From a gameplay perspective, I lost my way a few times and couldn't really figure out what to do to finish the game. Also, the darkness sound is quite high pitched and made my tinnitus go crazy but good job of having an option to lower the volume. Overall this game is good but can be great with some gameplay tweaks.
