I like the aesthetic of the game. The simple yet colorful presentation reminds me a bit of old-school computer graphics from the 80s and the design really works well with the theme of Cthulhu. The music as well works great with the art.
The game itself is quite interesting and I think the cards explain themselves quite well. I think what might help is more visual indicators to show whether or not I am doing well in the game. This is because at some points I was unsure if I was winning or not and after 4 turns the game stopped letting me pick cards.
In general though, this is a pretty interesting concept and I think you did a good job especially considering that you were sick while developing the game. Hope you are feeling better now!
