+## Changes from tutorial
+* Added a macro to register components for `specs`, like was in the tutorial for saving/loading. 
+* Game state machine is moved to `src/state.rs`
+* Colors (Bracket-lib `RGB` struct) have been converted to static values in `src/colors.rs`, to cut down on boilerplate and numbers of ways of generating color values.
+* All references to `rltk` have been converted to `bracket_lib`, as `rltk` was a facade in `bracket_lib`
