Very cool spin on the tower defense genre. You need to know exactly what you want to do before going into every wave. And the fact that you have no control over the order of plots you visit, combined with building while the wave is happening means plans can change and you'll have to adapt on the fly. Do I build on the plot I'm at right now while enemies are still en route? or do I wait for a better position and hope my current defenses can hold up?
I did end up playing exclusively on speed 3 because anything below is just way too slow, and got to the end (cool win screen btw)
Overall a simple idea with a lot of potential, something like if there's an option to hold down space to skip to the next plot, but at the cost of a little bit of gold, would already add a ton of interesting decisions to the game.
