Once the design was finalized I began implementing how the upgrades would tie into progression. Through Rise from Ruins waved based format, points would be given to the player to spend on new abilities or upgrades to said abilities. With the player needing to purchase an ability than each subsequent upgrade, with each each purchase unlocking a new upgrade. This intended to invoke a feeling of constant enchancement, as each round the player would receive a new upgrade and be shown the next step they could take. As the project was nearing completion, the number of total wave and in turn points the player would recieve was reduced, so the points needed to gain a new ability was reduced from two to one, in order to keep the same trajectory of player improvement over a shorter time.
