Thanks for your comment!
A little explanation on the design: One problem I have with the card design is how to design the first infect card. At first, I made it so that it could only be used once (just like the "infect once" card you see in later levels), so it wasn’t that powerful. But then I realized that players—especially in the early stage—might not know how to spread the virus using other cards, and they might lose quickly. So I changed the infect card to its current ability. However, now it has another problem: the infect card is too powerful. If you keep using it and ignore the time limit, you can infect everyone. That’s one of the reasons I didn’t add the “don’t pick up a card” feature, as I intentionally want players to pick a card to lower the chance of getting this powerful infect card. It’s a design issue I need to think more about.
But thanks for playing and thanks for your comment!
