You know that bit in Scooby Doo cartoons where the gang rushs between doors in a long corridor, entering one room and emerging from another, seemingly disconnected door further down the hallway?
Well, that's a bit like how it felt to play new sci-fi puzzler Tiny Space Adventure.
You take control of an astronaut who must navigate a series of doors to reach an exit. Along the way, you have to avoid getting frazzled laser barriers, or spotted by robot sentries.
As you're popping in and out of identical-looking black doors, you need a decent memory and a good mind for pattern recognition to be successful. Which probably explains the trouble I had reaching the end of some of the levels.
