Thank you for playing! Were you able to store/release the villagers in order to switch lanes? When you say stuck do you mean the game crashed or you were unable to move forward?

Gotcha! In the game, you are meant to have the villagers "switch lanes" by sending them home, storing them in the house, and releasing them at a different house. I believe you got stuck because you were not able to switch a villager onto a new lane in order to have them harvest gold. This will be something I address in the game design, thank you for your feedback!
