Thanks for the feedback on the art! The 0 cooldown is intentional as we wanted the player to be as fast as possible. If you spam the buttons you'll probably make a lot of flawed mixtures (the black ones). You may get away with it at early levels but I don't think it would work for end-game. Did it work for you even then? Nevertheless, if we expand on the game we could come up with a score/combo system where you'd be penalized for missing. Thanks for playing!
