Thank you for playing! It kinda intends to work that way, the timer starts when the flow rate of the source is not met because the path is already full. However, because the pathfinding has some bugs and could be greatly improved (it was my first time), and I only had time to test the game up to some score, it comes a point where the number of exits might not be enough to sustain the number of sources. I’d love to make it more playable by fixing the pathfinding and by balancing the spawns, that way it could truly be endless! I really appreciate the feedback :D
