List of changes and progress since last thread:
- All Pokémon have finished stats and learnsets.
- 2/3rds~ of Pokemon have fixed movesets. (Every Pokemon needs a changed moveset since most of the moves are gone.) Some Pokemon have received new moves as a result. (For instance, Tangrowth learns Recover and Houndoom learns Thunderbolt.)
- Basic facility sets have been planned for all non-legendary pokémon.
- Added simple debug menu with battle test.
- Upgraded mechanics of old moves, implemented all new moves. No move animations yet.
- First two maps added to the game, but are yet to be filled.
