Nitrome usually thinks big, but some of their best work is when they keep things small... really, really small! Flue is a puzzle game that, like Turnament, Ice Beak, and J-J-Jump before it, is a mere 50x50 pixels. Don't worry, you can make it bigger if you need to! Just click the screen to bring up a menu, and the icon in the lower left corner will make the game larger incrementally. Using [WASD] or the [arrow] keys, you're guiding some green goop through a series of tunnels to the exit in each stage. You're moving away rather than left or right, but if you bump up against the wall on either side of you, the world will rotate ninety degrees in that direction, as long as there's a platform for you to walk (ooze?) on. If you encounter a hole, it can be filled by pushing one of the little round balls into it to create a new platform. Just think carefully about where you're going, since the game is turnbased, and enemies move when you do!
It's hard to make a game this small engaging rather than repetitive, but Nitrome has pulled it off again. Levels are smart rather than simple, especially once the game begins introducing new elements later on, such as teleporters that spit you out around the area, or hazardous spikes that appear after every few moves. The one-hit KO is a little frustrating, especially when some levels take so much careful finagling and maneuvering, and for some players keeping a mental map of each level's layout might be more challenging because of the game's distinctive design. Still, Flue's tricky and constantly evolving level design will keep you on your toes (metaphorically speaking, you cute little blob of snot, you), and makes for a satisfying chunk of puzzling action... perfect for a coffee break!
