Nice game! There is one thing that annoys me: you can't turn off the Autobuyers (or at least I haven't figured out how). Some autobuyers will always upgrade ASAP after getting another upgrade (I RUN, The Witch of LOREDelith) and will put their inputs in the negative, which prevents the other autobuyers with this input from upgrading even though they use a tiny fraction of the input. I would love a "Crumbs" mode where the autobuyer never puts its input in the negative.
