Obviously not my cup of tea, but it seems nice regardless.
My biggest issue in my admittedly very short time of playing is just the tutorial.
Nobody likes tutorials, and especially nobody likes reading and memorizing through instruction manuals. The best of games teach their mechanics through the course of the game, or failing this, just introducing new rules AFTER you've grasped the previous one, rather than unloading everything all at once.
For such a game as this, I would wish that, in starting, the instruction manual appeared and guided the player through the process of the learning curve.
