An incredibly dense Pokemon romhack. Probably the most feature complete Pokemon hack ever made. It's incredibly polished. The game is long, and the difficulty options are robust and well thought out. The design is tight, with nothing breaking the experience, or causing prolonged grinding. The map/dungeon design is great. The post game is excellent too.
The only downside to the game is that it's more interested in being faithful instead of adding new content. There are no fakemon, no stat/type changes, and no new moves or abilities. There are plenty of battle modes that have interesting twists, but sometimes those come across as gimmicky instead of fun.
Also, another minor nitpick is that there are "puzzles" that are essentially stealth missions where you can't be spotted by roaming NPCs. Stealth missions really don't work in a grid-based RPG. I'd recommend setting the puzzle difficulty to "easy" to avoid them.
