 ## TODO
 Currently the game is lacking a few features which are still in development:
-- Game saves
+- ~~Game saves~~ Game saves have been added! They currently store coins, but storing the hi-score is still a work-in-progress.
 - Coins/currency
 - Powerups
 I am also working on a "story mode," which incorporates different powerups and such and works kind of like a step-by-step introduction to all of the elements in the game (most of which have not been added yet). I am also trying to figure out a workflow in which I can add a `beta` branch to `GitHub` in order to introduce some new features beforehand so that they can be tested out.
