Hi! I haven't posted yet, but I've been keeping up with this and look forward to reading more in the future. To respond to some things so far:
-I'm happy that people like the concept of being able to choose any (non-legendary) starter. It wasn't something that was in Spork originally, but after I remembered a conversation I had with someone where the idea was brought up, I remembered liking the sound of it and decided to do it.
-Re "...oh, no...": the Mega Ring will not be available until episode 6. You're able to find mega stones, but not use them yet. XY and ORAS made them not appear until you actually obtained the Mega Ring even if you've already been to the places they're at, but I didn't see a point or need for that.
-Pheromosa: the reason it's available at that specific time and place is because someone who knew about Spork since before it was being worked on suggested it and gave details for the event. I actually don't do the "it's too early for this Pokemon/item/TM" etc. thing when making Spork. While I do genuinely try my best to have Gym Leaders, rivals, etc. put up an appropriate fight with their movesets and items, Spork isn't necessarily intended to be difficult, and I don't necessarily believe that some Pokemon are inherently better than others in battle.
-walking through the wall: thank you for mentioning that. I've fixed it now. The issue was that while the wall in the tileset was non-passable, the edges of the doors weren't, so the player could walk through the part of the wall near the doors.
-Team Portal: they're another part of the game I'm glad people are enjoying. I won't spoil anything, but I will confirm that they aren't trying to take over the world. I'll also say that the leader and each admin have their own individual reasons for being a part of it (the specifics of which will be revealed in episodes 5 and 6).
