How to remove placed buildings? This is absolutely necessary because of the price scaling.
Thanks for the comment. In my view, a strategic decision implies long-term consequences that are beneficial in some cases and detrimental in others. This derives some degree of irreversibility of such decisions. Not being able to replace buildings is a high degree of irreversibility.
You can say that the action of payment for buildings and the effect of increasing prices is also a form of irreversibility by itself. And I agree that this is the case with most incremental games. However, my vision is to have a strong emphasis on the spatial dimension of the game. So I want placement to be an important decision, with upsides and downsides.
