About some criticism: The overworld is not really that big, you can see everything in 5 minutes, it's only a small part of Classic. Also it's called Classic because it's Classic
The game play of Classic is what Graal made a success. The frame rare is 20 fps, the speed of players is 0.6 tiles per frame instead of the default 0.5 fps to make it feel more fluid / less laggy and have a chance against PC players. It's showing the grab animation when you press A to give some feedback, pressing a button should always give a visual feedback. Currently there are no other items beside bow, bomb and sword so a Q menu would be pointless. You can tap on the player to see the player profile which shows your current amount of gralats.
