Future plans

Once I have gotten the game into a completable state from start to finish with as few bugs as possible, I plan on doing the following;
– Adding in Gen 5 Pokémon.
– Adding a Nuzlocke mode into the game.
– After finding a script hidden in game for dive spots, I’m thinking I may add in some post-game shortcuts for certain areas (for example a direct route from Goldenrod to Olivine via route 34) and will be using them to facilitate access to Gen 3 (and maybe Gen 4 also) legendaries
