Humorous game haha. I think caffeine (it was misspelt as 'caffine' in the game) actually harms your brain, but there was no effect on the brain in the game. Also, getting a doctorate negatively impacts one's emotions, and some studies have compared the level of stress of getting a doctorate degree with the death of a close family member - they found out that getting a doctorate feels more stressful and painful than that.
It was only later on that I realised there is a scroll bar on the right. It should be clearer that it is a scroll bar, otherwise it might be overlooked.
The dark blue colours of the rainbow spectrum used for the words do not contrast very well with the dark background. It could be changed to a lighter hue.
Cool concept :)
