I played it in browser if it's relevant but after I unlocked the chocolate sauce the percentage of it is way glitched if the cup isn't full.
When you pour in chocolate sauce it shows it has some insanely high percent of chocolate sauce, like 1500% or something like that, and as you fill the cup up it'll gradually lower to 100%. If you have multiple ingredients in a not-full cup, the other ingredients will properly show what percent of the cup they're filling, but the chocolate sauce will still have some insanely high percentage until you fill it up full, then it'll show its proper percentage.
Only glitch or issue of any kind I noticed in this game. Don't know why the chocolate sauce would have its % calculated differently but I'm not experienced in game making,all I can do it make the glitch be known lol.
