Incredibly fun game, with a strong concept and a pretty good execution. Given the time constraints, I can't complain about the gameplay at all - it's got such a good feel, controls well & is responsive, the difficulty of the various sections is in a pretty good and consistent range, and the speed and colours are telegraphed well. I'd like the yellow and the orange to be a bit more distinct (maybe shift the orange up to red?) but otherwise, the art and theming is really good! Definitely incredibly replayable, if you had managed to get the depth/score feature in I would totally be playing this over and over to try and beat my high score. Great contribution to the jam! :^)
