Simple but well executed core gameplay, swapping colours to set up multiple shapes of the same colours was really addictive. Just a suggestion to add a little juice to the game, you could use different sound effects depending on how high the combo is (for example having a more spectacular sound when you hit 2 or 3 of the same colour in one hit). Retro soundtrack fit the minimalist art style well, overall very good submission to the jam, congratulations.
