Glad you enjoyed it!
- I have considered making a quiz like that, but the sheer amount of Pokémon available plus the prospect of updating it every time new options come out seemed like a bit too much for one person. The most I could maybe do is have a type quiz and then randomize which Pokémon you get within that type.
- You know, I actually haven't considered skill advancement. Apart from gaining new skills from levelling, there actually isn't any way to advance skills past +2. Maybe an IQ Talent or something would work for that purpose. ("Any current and future Major Skills give +4 instead, and Minor Skills give +2"?)
If you'd like to translate the game, I'd welcome it! Let me know what materials you need and I'll be glad to send them. (And obviously I'd credit you for your work both on the game's page and in the translated versions of the documents.)
