Here are the errors that I have so far, or just things that you can improve upon next release
-You have .mp3's in your game, but they are of the offical songs. To save file space, just use midi. Or use full .mp3 of music. It doesn't make much sense to use both midi and mp3.
-The keyboard commands when used to name characters is misleading. The "Z" key isn't an okay command.
-The trainer sprite of Red doesn't have a transparancy.
-Some of the text overlap into the text box border.
-The stairs in Red's room have a few white pixels which should be part of the transparent color. (Both sets of stairs.)
-Red's walking animation feels a little clunky. (Think, do I walk like that?)
-The PC in Red's room doesn't work.
-When Red says, "That's not how YOUR catch a Pokemon!" It's you, and the exclamation mark should be on the same line as the rest of the text. On the next line, it should say, "You have to weaken a Pokemon before you can catch it", or "You have to weaken Pokemon before you can catch them." On the next line, there needs to be a punctuation mark…
-Wild Nidorino sent out a Nidorino??? (I know you were doing that to prevent people from catching that Pokemon, but you don't even have any Pokeballs on you).
-When the letter I, is standing on its own, you capitalize it. Check all of the dialogue following the capture of Nidorino.
-Bugcatcher says, "Maybe he'll tach us to catch some!" Should be teach.
-All of the Rocket Grunts say the same thing. I think that you should add more features to them so that they don't sound so copy-pasted.
-The camper on Route one can't spell routes…
-The first camp site can be entered from the side. Just by walking along its edge.
-Red says, "Good…Those mean aren't here yet."
-I always here what sounds like Starcraft computer noises when I am in Pallet Town, is that normal?
-Takle is spelled Tackle.
-I'm going to stop talking about the punctuation, I'd fill up 30 pages of it, just read thru all the text and fix them. Grammar is really important.
-There are random cries being played at the intro to the Mew fight, as well as any other fight…hmm…particularly Bellsprout on the foe's side, and Feralagatr on my side.
-Pallet Town bridge has a black border. :/
-Fisherman on said bridge forgot about tenses.
-HUGE BLACK BORDER!!! OMG THE END OF THE WORLD!!! But yeah, careful with black edges around the game map.
-Game crashed upon entering the southeast house in Pallet. Says the map doesn't exist. Map048.rxdata.
-Same with the northwestern house, come on, man…
I hope these help so far.
