Pretty fun so far-
couple of bugs I noticed:
In the first town if you try to go down the path back toward the ship, the game freezes.
In the first town, in the bottom house after the lab explodes if you look at the trashcan in the right corner of the 2nd floor a white text box will appear and won't go away until you go downstairs. It does not happen before the explosion.
In that same house after the explosion, if you look at the tv on the first floor it gives the same dialog the trashcan on that floor gives. This does not happen before the explosion.
On route 5, there is a bug catcher (don't remember what the in-game name was) with a small tree to the right of him. The player is able to walk into the tree, so the top tile is above the player but the rest of it is hidden by the player.
Last thing I noticed, and probably the biggest issue (other than the game freezing).
I healed at the pokecenter in West Glockdale, but when my pokemon fainted I was brought back to the pokecenter in Fanny Barks. If it matters, I was using the attack form of Porygon and had no other Pokemon, and I lost against the gym leader.
