@jason6432 Personally, I wouldn't make a game as big as Pokemon with HyperPad yet.
HyperPad is still too limited to make such a game. It's possible, but you will quickly find it's hard to make new changes when you have a lot of content, and very unoptimised. No prefabs, no tile/Level Editor, not optimised for tile based levels.

HyperPad doesn't have a "tile" object yet, for creating games that uses tiles/tilesets. I asked them about this, they said for now it's recommended making the level as an image, because using that many scenery objects is not optimised enough. They did say they will make a tile object optimised for this sort of thing in the future though.
