Great concept but too capricious
I do like the concept, and I like the idea of things going wonky when you take too many pills. I got to see a few effects but not many.
The reason for this is that the pills don't seem to show up enough times. I was at about 10% white and didn't see a single pill until the bar started flashing red. At that time, pills showed up, but I couldn't get there in time.
I'm all for making things difficult as time passes (faster dice, pills are more and more off the ground, etc.), but this becomes difficult for no good reason. If the random number generator is not kind to the player, then the player loses through no fault of his own. That makes the game less fun.
Regulate the pills so that they are available consistently (even if you have to jump over 8 dice to get to them), and the game is very playable.
