Hey, thanks for the feedback! I completely understand why you thought there was nothing to explore, and yes, there isn't that much stuff to find in the map, mostly just the spawners. We thought about adding some other types of buildings, that just like you said, unlock some permanent upgrades for your towers, and we would have even liked to make the pathfinding better, but all of this was not possible because of time constraints, we frankly ran out of time. Trying to do a tower defense with world generation was something new for us, so we also had to learn all the stuff, so there wasn't that much time left to expand on the game idea.
