I just finished playing through and I really liked it and hope you continue unlike the guy who made white (old) version.
I've got a small bug report for you.
When I renamed my Bulbasuar to Suar after getting it, the spirte was an egg, not Bulbasuar, and after I named it, it's name went back to Bulbasur, not Suar like I wanted.
The very first guy (not the trainer) inside the first gym says that Flying and Water type pokemon are good against Rock types.
When using Cut, the trainer reverts to the original sprite.
Only about 50% of the trainers actually come and battle you when you walk in front of them.
Also, a little suggestion. Lower the levels of the trainer pokemon on route 52. They matched the last gym leader's pokemon, and the leader is supposed to be a challange, and the pokemon that follow should be about the same level as the gym trainers, not the gym leaders.
