Okay, the atmosphere was intense and the card battle system was a nice touch, but maybe a little bit too slow. Movement instead was fast and snappy. I too had a lock of my controls and could not do anything after acquiring a new card. I posted complains under some other Unreal engine games that I do not think that it is the right tool for the jam. The games are most of the time VERY large and have nothing to show for that size. Your game stood out of the Unreal crowd a bit and was quite beautiful and seemed to use some of the engine´s features well.
