Not sure it is just me, but on the web version it felt like the audio sync wasn't the best? Otherwise though, there's so much content here and it's a great little concept even if it doesn't stick to the theme particularly well. Visually it sticks to the shapes limitation and looks good - but it feels like there's something wrong visually - sorry but I can't put my finger on what it is at all! Maybe the font choice, maybe it is all the outlines, maybe it is the colours, I'm not sure but there's something that feels off.
Music is excellent, difficulty feels about right for a jam game, good job :)
