Very original idea ! I like it, it would just need some kind of ingame tutorial to help the player understand the mechanics, it can be a bit confusing currently. But once the mechanics are understood, it's pretty fun to play !
After a while, I noticed that sometimes, some proteins were not shown in adjacent cells, it is quite rare but happened a few times, I suppose it's a bug. I think it has something to do with the moment when new cards appear.
