Replaying X and was forced to visit this "castle" which doesn't seem to serve any purpose. Why even make an entire building with two floors just for the Pokeflute? It's like they wanted to include more lore in this location but just decided to scrap it and include it elsewhere. It feels like XY were designed as unfinished betas just like DP, which makes it all the more disappointing that we never recieved a Z version.
