I would like to say it is an interesting concept and it is fairly difficult trying to manage resources to protect the Pyre. It did take me a while that the movement was also used to attack creatures and grab resources but was able to figure it out similar to old 90s games. Gave a little bit of nostalgia with that.
I was only able to get through two waves of monsters before getting overwhelmed on my third wave during my playthroughs. I'd say it became increasingly difficult by the time I reached that point while also needing to travel further for resources. I also couldn't figure out how to feed/fix the Pyre, if that was possible but would be nice if I could.
I did find how some trees and stones took the same amount of damage but yielded different amount of resources a little weird. It would be nice if the trees and stones that yielded less resources required less hits and help with management. There were also a few instances where I accidentally placed/upgraded towers by moving too close when an enemy came into camp or holding the movement keys for too long.
