I liked the theme and the idea. It does give the impression of those shapes when you close your eyes at night, which are strange. Plus some plot was layered over the top, so that was great.
The visuals are apt and that they are generated in code is impressive.
What brought it down for me was the audio. Although the sound was alright and fit the theme while the game was going on, playing a single tone at high volume in my ear while I tried to read the dialogue wasn't something I could push through.
Well done for creating it all yourself in a week!
