I studied a Chemical specialization in the secondary school, but this is too difficult for me. I will keep trying, without seeing the video (I already have my two [Pyruvate]s!). Some comments: * Add an "undo" button. I'm not sure if it is possible to choose a bad reaction, but I’d like to undo some of the tries. (And perhaps a "restart+areyousure" button.) * Add a lithe graphic to each molecule, so they look more rea…
* Added delay for every reaction
* Made the page less tall, everything is smaller now (I'd underestimated the size, working on a 27" iMac)
* The easy mode was already there, enzymes lit up when you picked up a substrate. I've added an extra help now: when you hover over an enzyme, the available substrates light up.
* The transporters are only visible (and usable) if enough ATP/substrate is available
