It is true that the game is intended to be on the harder side, similarly to how there is no undo button and soft locks in games like Shenzen I/O Solitaire.
However, I can see how you could get in a position that would seem unfair, especially once things get out of control. We have some improvements in mind which we'll put them on a timeline after the game jam is over.
Thanks a lot for the feedback! It is highly appreciated.
