Only suggestions: I feel like there needs to be some sort of encouraging factor if you finish the ten minutes with no improvement to your previous attempt. I don't want to attempt again once I've realized I've failed and have to retry with a few different modifications.
There might be a reason why, but the distance between the storage house and woodchoppers seems to be longer than it needs to be. My runners already have to run to grab wood, then to the storage, and then back to the tower; why so distant?
This is also my first time posting to a community, and I didn't realize that it wouldn't save my progress, so starting everything over again seems daunting....but that one is totally on me, heh.
