A: This version of the game was remade from the ground up and only reaches Sudowoodo (much like v1 did, way back when). If you want to play the older, more "complete", but generally worse v2 from 2013, you can download it here.
Q: I found a bug/glitch/oddity!
A: Whoops, my bad (usually)! I'd appreciate it if you left me a comment down below, posted about it in the Discord server, or reported it on the thread at PokéCommunity.
