I really liked the infection mechanic on grid, it was deeply satisfying to see all those cells turning red! Also, the power-up cards that can be retained in the hand from one turn to the next, add a new layer of strategy that I didn't expect, but which I truly appreciated :)
Overall, the gameplay has a lot of interesting ideas, and it would be nice to see them further explored :)
Regarding the aesthetic, I think it really fits the gothic/vampire setting, but it becomes too dark sometimes and I had some troubles in seeing the game elements. The audio is really catchy, and I loved how it changes organically at the end of the day!
Great submission, congrats :)
