A lightweight and minimalist webapp that compiles all the locations of all Pokémon across every game in the series. It gives you instant Pokémon information and keeps track of your Pokédex progress.
Here are some improvements/fixes I want to suggest. I can work on some of them myself, though I am not that familiar with the code (yet).
Back button: Changing the game currently requires the user to scroll down to the bottom and click on "More games" which opens the "welcome page" in a new tab. I suggest having a back button at the top left of the page which brings one back to the initial page. That button and the language selector could be position:fixed (at least on Desktop).
Improve lang selection: The language selection seems a bit buggy right now. It doesn't save on the initial page, does not instantly update Pokémon names and doesn't save the Japanese language (jumps back to English upon reload).
Global lang setting: The user should only have to set the preferred language a single time. It should be one global value instead of seperate language settings for each game page.
index.html not fully translated: All of the index.html files have text blocks that can't be translated right now.
Make caught button available to all Pokémon: The button isn't there for some of the Pokémon in the national dex and that makes it impossible to mark them as being caught.
