Cursed park - I just completed the first puzzle to get the stones but the game is stuck on the screen where it shows the item you have picked up, but it won't actually go into my bag or let click anything else, including the settings button to try and restart the level. I've tried restarting the game and letting the timer run out to see if I can force it off that screen but I can't do anything. Does anyone know if you can reset a specific level before actually entering it?
