Thanks for the feedback !
The balancing is something that might need a retweak once the jam is over. I firmly believe that having a dice that allow to have a movement everyturn is not a good solution, because it remove a lot of constrain (if you manage your placement correctly, you should be able to fill any lane in any turn since you can warp from top to bottom and vice versa).
On the other hand, having no movement during 4 consecutive turn is a big issue. A nice thing we could implement is forcing the yellow dice to give you a movement if you didn't have a movement on any dice last turn.
Additionnaly, we saw the suggestion to be able to put shield and heal the core. Healing doesn't sound like a good idea but shielding the core is definitely something that I would like to implement
