Selling an upgraded tower should return a share of what the player really paid

A player upgrades a tower three times and then sells it. If the refund is based on the list price of the top level, discounts and sales promotions become free money; if it is based on the base price, upgrading feels wasted. This entry shows what to remember per tower and why selling in the middle of an attack should pay less.

Why this works

A refund is a statement about what the player gave, so it must follow what was actually spent, remembered at the moment of spending. Prices on a menu change with sales and patches, but a record of real payments does not. Paying less in a crisis makes selling a plan.

When not to use it

Skip it when selling is meant to be free and instant, such as a puzzle where the player rearranges pieces to try ideas. A loss there only punishes experiments. Refund everything, or let the player undo the last moves.
