Braid is a 2-D puzzle-platformer game developed for the Xbox Live Arcade. You play as the protagonist, tasked with rescuing an abducted princess by travelling through various worlds and solving puzzles. The unique twist of this game is that time can be manipulated in strange ways; you have special powers to rewind, create parallel universes, set up pockets of dilated time and more which are used to solve each puzzle. The gameplay is challenging but not punishing - death or loss cannot occur - and every puzzle introduces something new about the world. Braid's main focus is on valuing your time and attention; there are no filler elements present in this game so every moment spent playing it will reward you with something meaningful.

Marble Blast Ultra is the latest installment of the classic Marble Blast series, and it's suitable for players of any age. The game has you navigating your marble through a futuristic "astrolab" arena suspended in the clouds, with moving platforms and dangerous hazards to avoid while collecting gems and power-ups to help you complete each course quickly. You can also compete against other players online with Xbox Live's ultra blast multiplayer mode.
