Initially took me a while to get the game going as I had to install some extra visual c ++ components, which I think is typical of the Unreal engine. Game looks great and is very polished. It did take me a while to work out what to do, especially the bit about dragging the cells on to the cards. Perhaps an animation that demonstrates the movement could help explain that better than the diagram? Also, I did find the speed of the simulations a little bit slow, perhaps make it faster so it doesn't take as long between tries. Great work overall.
