Unfortunately we encountered some bugs, we will update on this later today. The mechanic for shifting the tiles is now fixed and will be implemented. However we still need some time to implement it. The cards will be explained in images in our itch.io page today as well, making it easy to understand what they do and how they work. This should give some more clarity. Players who will play the game tonight will notice a big difference. Thank you for taking the time to play our game in its current state.
