Very beautiful game, some outstanding art and animations. Just the dice roll animation itself wow'd me.
I have some terrible luck but I can clear the memory game very easily so i was able to beat the game but I "died" so many times.
Unsure if it was an intended effect but I managed to cheat the system, if you use a matching symbol on a patient symbol already activated it counts towards the total of active symbols cured, so I was able to clear some patients while they had unactivated symbols. (This helped me a lot cause certain situations I couldn't roll that one last symbol type I needed)
Only other suggestion I have is maybe a sort of way to tell you've already sued a die to activate a symbol.
Nice work.
