Just watched your stream (Three cheers for different time zones) and it was so interesting to see someone figure my little game out :). Besides, I like the timing idea as that pressure would make it way more challenging, but atm I'm not sure whether it's okay to add mechanics at will to my submission as it was technically submitted after the 72 hour period. As for the weird perfect drinks, the rating is all about proportions so if you go a little past the targets with all of the ingredients your drink will be fine, which also means that you can add the right number of drops of what you need and get a perfect 50ml drink but let's not :P
