Amazing game! I loved Solitaire at the time, and playing this was such a peaceful and emotional experience *-*
The idea of representing parasites as sequences of cards is perfect, and I was surprised by how well the solitarie mechanics fit on that core idea. On the other side, the additional "Roshambo" mechanic felt a bit unrelated, also because (but I may be wrong here) there's no way to strategize your move, it's more like a random guess?
The "artistic" side is simply beautiful: the animations are smooth, the music is relaxing, the cards are clear but also unique in their way. I don't know if you designed the graphics, but I would pay for a deck of cards with this style :P
Overall, fantastic submission! Congratulation for your first GWJ :)
