Fez

- Take notes. There's a glyph language for letters, numbers, and inputs and you'll want to puzzle out all three to get the most out of the game.

- You can't solve every puzzle until New Game+.

- When you unlock a new cube room you'll want to go there first - the areas behind are small and tend to have important information in them.

- Generally just explore everywhere you can, the game's huge and has a fantastic amount of interesting areas to discover.
