This is unfinished, sorry. So open world will always be locked! So just chat with the cat for a bit, then click the app, and see how far you can get until you get to the part where it is unfinished. Updates coming: button up and down movement, new button that starts a battle and you need to beat the monster to unlock open world, open world will be a scrolling (I hope scrolling but probably not) level where you explore a world of monsters that you can beat, a button to enter "level" it will bring you to a screen with level numbers click the one you want to play it brings you the level and at the end you go in a castle to fight a monster.
